Description

하·폐수 처리장의 수요반응 서비스 시스템Demand response service system of sewage and wastewater treatment plant
본 발명은 하·폐수 처리장의 수요반응 서비스 시스템에 관한 것으로, 더욱 상세하게는 하·폐수 처리공정의 전력부하, 에너지 저장설비 및 재이용수 등을 활용한 신재생에너지를 설비를 하·폐수처리장 별로 최적 운영하여 수요반응 서비스 자원을 확보하는 하·폐수 처리장의 수요반응 서비스 시스템에 관한 것이다.The present invention relates to a demand response service system of a sewage and wastewater treatment plant. More specifically, the present invention relates to renewable energy utilizing power loads, energy storage facilities, and reused water in sewage and wastewater treatment plants. The present invention relates to a demand response service system of a sewage and wastewater treatment plant that optimally secures demand response service resources.
일반적으로 전력망은 전력의 수요와 공급이 서로 일치하게 운용되도록 설계되어 있다. 이 균형을 나타내는 지표가 주파수로서, 이 주파수의 안정성이 전기의 품질과 직결된다.In general, power grids are designed so that the supply and demand of electric power are consistent with each other. The index indicating this balance is frequency, and the stability of this frequency is directly related to the quality of electricity.
현재 전력망의 운용에 있어서, 전력의 수요는 개개인의 전기 사용에 따라 달라지는 것이므로 이를 조정하기는 매우 어렵다. 따라서 전력공급이 항상 전력수요에 실시간으로 따라가도록 하고 있다.In the operation of the current grid, the demand for electricity depends on the individual electricity use, which is very difficult to adjust. Therefore, the power supply always follows the power demand in real time.
그러나, 전력수요가 시간에 따라 크게 변동하기 때문에 전력공급량은 항상 최대수요를 감당하도록 되어 있다. 최대 10% 수요는 사실상 1년 365일 중 3일 정도이므로 이 3일을 위하여 수많은 발전기가 일 년 내내 대기하고 있는 것이다. 이것은 마치 추석 연휴 3일을 위하여 일 년 동안 사용하지도 않는 별도의 고속도로 시설을 유지하고 있는 것과 마찬가지로 비경제적이고 비효율적이다.However, since power demand fluctuates greatly with time, the amount of power supply always meets the maximum demand. Up to 10% demand is virtually three out of 365 days a year, so many generators are waiting for the three days. This is uneconomical and inefficient, just as it maintains a separate highway facility that is not used for three years during the Chuseok holiday.
만일 일년 중 최대 수요가 일어나는 3일간만 수요를 10% 줄일 수 있다면 전력망 운용이 매우 안정될 뿐만 아니라 국내의 경우 5 내지 6개의 대형 원자력 발전소를 건설하지 않아도 되는 것으로 그 경제적 이득은 매우 크다.If the demand can be reduced by 10% for only three days when the maximum demand occurs during the year, the grid operation is not only very stable, but in Korea, it is not necessary to build five or six large nuclear power plants, and the economic benefit is very large.
이러한 점에서 수요반응(Demand Response: DR)에 의한 수요관리기술이 대두하게 되었다. 특히 전력 수급의 적시성에서 약점이 있는 신재생 에너지원의 증가에 따라 수요반응이 더욱 필요하게 되었으며, 전 세계적으로 진행중인 지능형 전력망인 스마트 그리드(Smart Grid)가 구축될 경우 수요 반응은 핵심적인 서비스임이 분명하다.In this regard, demand management technology by Demand Response (DR) has emerged. In particular, demand response has become more necessary due to the increase in renewable energy sources, which have weaknesses in the timely supply and demand of electricity supply and demand, and when the smart grid, which is an ongoing global power grid, is established, demand response is a core service. Do.
보다 구체적으로 수요반응이란 전력수요가 증대할 때 이에 수요자가 반응하여 전력사용을 줄이는 것으로 수요자의 수가 많기 때문에 이를 일일이 조정하기란 매우 어렵고, 현재 전력 시스템상으로 전력망 운용자가 조정할 수 있는 방법은 계획정전 이외에는 없다.More specifically, the demand response is a response to the increase in power demand, which reduces the use of electricity. Since there are a large number of demands, it is very difficult to adjust them individually. There is nothing else.
특히 단순한 전력 요금체제를 가지고는 수요자가 자발적으로 반응할 만한 동기가 부여되지 못하기 때문에 미국이나 유럽 등지에서 다양한 요금제를 기반으로 기본적 수요반응을 발생시키면서, 전력망 운용자가 수요반응에 대한 강력한 인센티브를 부여하는 방식, 더 나아가 시장에서의 판매를 통하여 더욱 활발한 수요반응 서비스들이 적용되고 있다.In particular, since a simple electricity tariff system does not motivate consumers to voluntarily respond, the grid operator generates strong demand incentives for demand response while generating basic demand responses based on various tariff plans in the US and Europe. More demand-response services are being applied to the market through sales and in the market.
국내에서도 하절기나 동절기에 전력사용량은 매년 신기록을 갈아치우며 급격히 높아지고 있다. 이렇듯 전력 예비율이 5%도 되지 않는 상황이 벌어지고 있어서, 전력 부족 사태가 벌어질 경우 발전소나 송배전 시스템, 그리고 중요한 시설 등이 직접적인 전력사고의 피해자가 될 가능성이 높다.Even in Korea, the electricity consumption in the summer or winter season is increasing rapidly, changing the record every year. As the power reserve rate is less than 5%, power shortages, power transmission and distribution systems, and important facilities are likely to be victims of direct power accidents.
이러한 전력부족으로 인한 사고를 예방하고 추가로 발전소를 짓는 비용을 줄이기 위해 한전과 전력거래소는 실시간 DR(Demand Response: 수요반응)의 상용화를 추진하고 있다.To prevent accidents caused by power shortages and to reduce the cost of building additional power plants, KEPCO and the Korea Exchange are pushing for the commercialization of real-time demand response (DR).
실시간 수요반응(DR)은 신재생 에너지를 통해 발전한 전력을 판매하는 전력시스템과 함께 스마트 그리드의 양대축을 이루는 기술로써, 발전과 전력 사용에 수요/공급 개념을 도입하여 실시간으로 전력 사용 절감신호를 보내주고 이에 맞추어 수동 또는 자동으로 전력을 줄일 경우 이를 금전적으로 보상을 해주는 시스템이다.Real-time demand response (DR) is a technology that forms a major axis of the smart grid along with a power system that sells electricity generated through renewable energy. It sends power-saving signals in real time by introducing the demand / supply concept in power generation and power use. It is a system that compensates financially when power is reduced manually or automatically accordingly.
이와 같이 공공 시설물에 수요 반응서비스를 적용함으로써 효율적인 전력 공급과 소비의 관리를 위한 공공 수요 반응 서비스 제공 장치 및 방법이 한국공개특허 제10-2013-0082673호에 개시되어 있다.As described above, an apparatus and method for providing a public demand response service for efficiently managing power supply and consumption by applying a demand response service to public facilities are disclosed in Korean Patent Publication No. 10-2013-0082673.

And converts renewable energy including geothermal, biological organisms, and the like into energy and supplies it to a number of sewage and wastewater treatment plants 30 and large energy storage systems 40.
부하관리 사업자(20)는 다수의 부하(負荷)자원, 예를들면 다수의 하·폐수 처리장(30) 또는 일반 말단 수용가들을 부하관리 서비스 서버(21)를 통해 가입을 받고 상기 다수의 하·폐수 처리장(30) 또는 일반 말단 수용가들에게 부하관리 서비스 서버(21)를 통해 부하삭감을 공지하여 다수의 하·폐수 처리장(30) 또는 일반 말단 수용가들이 전기부하를 제어하도록 함으로써 수요반응자원을 관리한다. The load management company 20 receives a plurality of load resources, for example, a plurality of sewage and wastewater treatment plants 30 or general terminal customers through the load management service server 21 and receives the plurality of sewage and wastewater. By managing the load reduction through the load management service server 21 to the treatment plant 30 or the general terminal customers, a plurality of sewage and wastewater treatment plants 30 or the general terminal customers control the electric load, thereby managing demand response resources. .
다양한 포트폴리오를 통해 최적화된 수요반응자원의 조합을 이끌어 내어 전력망 사업자(10)의 수요반응 서비스 서버(11)에 접속하여 수요자원시장에 참여하여 수요반응자원을 제공한다. It draws the optimized demand response resource combination through various portfolios, accesses the demand response service server 11 of the grid operator 10, participates in the demand resource market, and provides the demand response resource.
여기서 부하관리 사업자(20)는 다수의 말단 수용가들을 모집하여 전력망 사업자(10)의 수요자원시장에 참여하는 주체로써, 수요자원시장에 직접참여할 수 없는 상기 다수의 하·폐수 처리장(30) 또는 말단 수용가들(예를 들면 중소기업, 일반 가정집 등)은 부하관리 사업자(20)를 통해 간접적으로 수요자원시장에 참여할 수 있다. Here, the load management company 20 is a subject who participates in the demand resource market of the power grid operator 10 by recruiting a plurality of end users, and the plurality of sewage and wastewater treatment plants 30 or the terminal which cannot directly participate in the demand resource market. Consumers (eg SMEs, homes, etc.) can participate in the demand resource market indirectly through the load management provider (20).
다수의 하·폐수 처리장(30)은 부하제어장치(34)를 구비하여 상기 부하관리 사업자(20)의 부하관리 서비스 서버(21)와 통신을 통하여 각각의 하·폐수 처리장(30)의 부하용량, 부하의 종류 등을 등록하고, 수요반응 이벤트를 수신하여 하·폐수 공정설비(31)와 에너지 저장설비(32) 및 신 재생에너지 설비(33)를 제어하여 상기 부하관리 서비스 서버(21)에서 할당받은 부하삭감량을 달성한다.The plurality of sewage / wastewater treatment plants 30 includes a load control device 34, and load capacity of each sewage / wastewater treatment plant 30 through communication with the load management service server 21 of the load management company 20. Registers the type of load, receives a demand response event, and controls the sewage / wastewater process facility 31, the energy storage facility 32, and the renewable energy facility 33 to the load management service server 21. Achieve the assigned load reduction.
부하제어장치(34)가 제어가능한 전력부하자원은 하·폐수 공정설비(31)에서 생성되고 에너지 저장설비(32)에 저장되어 수요반응 이벤트 시에 에너지 저장설비(32)에 저장된 전기 에너지를 활용하여 부하삭감량을 달성할 수 있으며, 신 재생에너지 설비(33)를 활용해서 생성된 전기 에너지도 에너지 저장설비(32)에 저장하여 수요반응 이벤트 시에 에너지 저장설비(32)에 저장된 전기 에너지를 활용하여 부하삭감량을 달성할 수 있다.The power fault source controllable by the load control device 34 is generated in the sewage and wastewater process facility 31 and stored in the energy storage facility 32 to utilize the electric energy stored in the energy storage facility 32 in the event of a demand response event. The load reduction amount can be achieved, and the electrical energy generated by using the renewable energy facility 33 is also stored in the energy storage facility 32 to utilize the electrical energy stored in the energy storage facility 32 in the event of a demand response event. Load reduction can be achieved.
하·폐수 공정설비(31)에서 소요되는 전력부하자원은 시간에 따라 가변이 가능하고 하·폐수 처리공정에 영향을 미치므로, 기술적 엔지니어링을 통해 하·폐수 처리공정에 영향을 미치지 않으면서도 빠른 시간에 생성할 수 있는 전력부하자원을 얻을 수 있다.Since the power source sources consumed by the sewage and wastewater process facilities 31 can be changed according to time and affect the sewage and wastewater treatment process, it is possible to have a fast time without affecting the sewage and wastewater treatment process through technical engineering. You can get the power fault source that can be generated.
또한 하·폐수 처리장(30)에서 일률적인 전력 부하자원이 생성되는 것은 아니고 공정이 일반화된 하·폐수 처리장(30)이기는 하나 운영패턴이나 방식, 주변 환경, 유입수량, 방출수량, 방출수 수질 등에 따라 가변의 폭이 크다.In addition, although a uniform power load resource is not generated in the sewage and wastewater treatment plant 30, the process is generalized, but the wastewater and wastewater treatment plant 30 is generalized, but the operating pattern or method, the surrounding environment, the amount of inflow, the amount of discharged water, the quality of discharged water, etc. Therefore, the width of the variable is large.
하·폐수 처리장(30)의 에너지 저장설비(32)는 심야 전력 등과 같이 요금이 가장 낮은 경부하시 전기를 충전하고 하루 중 부하량이 최대가 되어서 요금이 가장 높은 최대 부하시 수요반응 이벤트가 발생하면 하·폐수 공정설비(31)에 전력을 공급하여 전력망 사업자(10)로부터 공급받는 전력을 최소화하여 수요반응에 참여하여 인센티브를 받음으로써 전력 사용비를 절약할 수 있다.The energy storage facility 32 of the sewage and wastewater treatment plant 30 charges electricity at light loads with the lowest rates such as midnight power, and when the demand response event occurs at the maximum load with the highest charge during the day. Supply power to the wastewater process facility 31 to minimize the power supplied from the grid operator 10 to participate in the demand response to receive incentives to save power consumption costs.
전력 부하관리와 같은 인센티브 프로그램에 적용하여 전력망 사업자(10)로부터 높은 인센티브를 받을 수 있으며, 각각의 하·폐수 처리장(30)은 에너지 저장설비(32)를 활용하여 수요반응 이벤트에 참여할 수 있을 뿐만 아니라 전력망 사업자(10)에게 전력을 판매할 수 있으며 수요반응 이벤트에 참여하여 전력간축에 따른 인센티브를 받을 뿐만 아니라 전력판매에 의해 판매이익을 얻을 수 있다.By applying to incentive programs such as power load management, you can receive high incentives from the grid operator 10, and each sewage and wastewater treatment plant 30 can participate in demand response events using the energy storage facility 32. In addition, it is possible to sell power to the grid operator 10 and participate in the demand response event to receive incentives due to the reduction of power, as well as to obtain a sales profit by selling electricity.
일반적으로 에너지 저장설비(32)를 가지고 있는 하·폐수 처리장(30)인 경우 에너지 저장설비(32)의 최대용량을 부하자원으로 활용한다. 그러나 피크 저감을 통한 기본요금 절감 등 요금제 효과를 보기 위해서는 고객기준부하(Customer Baseline Load:CBL)관리가 중요하다. 에너지 저장설비(32)의 최적용량을 선정하고 시간 및 상황에 따른 최적의 방전용량을 산출하여 에너지 저장설비(32)를 전력 부하자원으로 사용할 수 있도록 한다.In general, in the case of a sewage and wastewater treatment plant 30 having an energy storage facility 32, the maximum capacity of the energy storage facility 32 is used as a load resource. However, customer baseline load (CBL) management is important to see the effects of the rate system, such as reducing the base rate through peak reduction. By selecting the optimal capacity of the energy storage facility 32 and calculating the optimal discharge capacity according to time and situation, it is possible to use the energy storage facility 32 as a power load resource.
신 재생에너지 설비(33)는 전력망 사업자(10)를 통한 구매전력과 별개로 하·폐수 처리장(30) 자체적으로 설치하고 발전하여 사용할 수 있으며, 전력부하관리로 신 재생에너지 설비(33)를 활용하여 에너지 저장설비(32)에 충전한 후 전력부하관리 이벤트 시 에너지 저장설비(32)에 충전된 전력을 사용하여 전력망 사업자(10)로부터 공급받는 전력을 최소화하여 전력 사용비를 절약할 수 있다. Renewable energy facilities 33 can be installed and developed by sewage / wastewater treatment plant 30 itself separately from purchase power through the grid operator 10, and utilize renewable energy facilities 33 as power load management. After charging to the energy storage facility 32 to minimize the power supplied from the power grid operator 10 by using the power charged to the energy storage facility 32 in the power load management event it can save the power usage cost.
신 재생에너지 설비(33)는 충전·방전의 면에서 보면 에너지 저장설비(32)와 흡사하지만 실제적으로 충전시간이 불규칙하고, 태양광의 경우 낮시간 특히 피크시간대 충전량이 많은 점 등을 고려할 때 피크 시간대에 에너지 저장설비(32)에 생산된 전력을 저장하여 시간대별 최적화를 얻도록 한다.The renewable energy facility 33 is similar to the energy storage facility 32 in terms of charging and discharging, but in practice, the charging time is irregular, and in the case of sunlight, the peak time zone is considered in consideration of the fact that there is a large amount of charge during the daytime, especially the peak time. To store the power produced in the energy storage facility 32 in order to obtain time-phase optimization.
각각의 하·폐수 처리장(30)은 부하자원 이벤트에 참여하는 방법이 각각의 하·폐수 공정설비(31)와 에너지 저장설비(32) 및 신 재생에너지 설비(33)에 따라 운영패턴이나 방식, 주변환경, 유입수량, 방출수량, 방출수 수질 등에 따라 다양하다.Each sewage / wastewater treatment plant 30 has a method of participating in a load resource event according to its operation pattern or method according to each sewage / wastewater process facility 31, an energy storage facility 32, and a renewable energy facility 33. It varies depending on the surrounding environment, inflow, discharge, water quality.
특정 지역의 홍수로 인해 특정 하·폐수 처리장(30), 예를 들면 1번 하·폐수 처리장(30-1)의 하·폐수 공정설비(31)의 풀 가동이 필요한 상황일 때, 1번 하·폐수 처리장(30-1)은 부하자원 이벤트에 참여가 불가능하다.When there is a need for full operation of the sewage / wastewater treatment plant (30) of a specific sewage / wastewater treatment plant (30), for example, the first sewage / wastewater treatment plant (30-1) due to flooding in a specific area, The wastewater treatment plant 30-1 cannot participate in the load resource event.
이런 상황에서 다수의 하·폐수 처리장(30)을 운영하는 부하관리 사업자(20)는 포트폴리오 상 참여가 어려운 1번 하·폐수 처리장(30-1)을 대신하여 추가적 참여가 가능한 2번 하·폐수 처리장(30-2)의 전력자원을 투입한다.In such a situation, the load management operator 20 operating a plurality of sewage and wastewater treatment plants 30 can replace the sewage and wastewater treatment plant 30-1 which is difficult to participate in the portfolio. Power resources of the treatment plant 30-2 are input.
도 1b에 도시된 종래의 기술에 의한 수요반응 서비스 시스템을 볼 때, 부하관리사업자(2)가 운영하는 LA서비스 서버(2a)에서 개별적으로 하·폐수 처리장(3)의 자원과 참여실적을 평가하고, 각각의 하·폐수 처리장(3)의 자원과 참여실적은 서로에게 전혀 영향을 미치지 않는다.In the demand response service system according to the related art shown in FIG. 1B, the resources and participation performance of the sewage / wastewater treatment plant 3 are individually evaluated by the LA service server 2a operated by the load management company 2. In addition, the resources and performance of each sewage and wastewater treatment plant 3 do not affect each other at all.
즉 성적이 좋은 하·폐수 처리장(3)은 높은 성과로 인센티브를 받으며, 성적이 나쁜 하·폐수 처리장(3)은 페널티로 인해 최소의 인센티브 또는 인센티브가 없게 된다.In other words, high-grade sewage and wastewater treatment plants (3) receive incentives for high performance, and poor-grade sewage and wastewater treatment plants (3) have no minimum incentives or incentives due to penalties.
본 발명에 의한 하·폐수 처리장의 수요반응 서비스 시스템(100)은 도 2에 도시된 바와 같이 부하관리사업자(20)의 부하관리(LA) 서비스 서버(21)는 다수의 하·폐수 처리장(30)을 각각 별개로 보지 않고 전체 하·폐수 처리장(30)을 취합해서 하나의 덩이로 보고 부하관리(LA) 서비스 서버(21)에서 모니터하고 관리한다.Demand response service system 100 of the sewage and wastewater treatment plant according to the present invention is a load management (LA) service server 21 of the load management company 20 as shown in Figure 2 is a plurality of sewage and wastewater treatment plant 30 ), The entire sewage / wastewater treatment plant 30 is collected and viewed as a lump without being separately viewed and monitored and managed by the load management (LA) service server 21.
참여 성적이 좋은 하·폐수 처리장(30)과 참여성적이 좋지 않은 하·폐수 처리장(30)이 성과 측면에서 서로 상쇄되고, 상쇄 이후 음의 인센티브 결과가 나오게 되면 성과가 좋은 하·폐수 처리장(30)도 인센티브를 받지 못하는 위험이 있으며, 양의 인센티브 결과가 나오면 성과가 나쁜 하·폐수 처리장(30)도 적지만 인센티브를 받을 수 있다.If the sewage and wastewater treatment plant (30) with good participation scores and the sewage and wastewater treatment plant (30) with poor participation scores are offset each other in terms of performance, and the negative incentive results after the offset, the sewage and wastewater treatment plant with good performance (30) ), There is a risk of not receiving incentives, and if a positive incentive result is obtained, even a poor performance of sewage and wastewater treatment plants (30) may be incentives.
대형 에너지 저장 시스템(40)은 부하관리사업자(20)의 부하관리(LA) 서비스 서버(21)가 전체 하·폐수 처리장(30)을 합산하여 관리하기 때문에 참여성적이 좋지 않은 하·폐수 처리장(30)의 전력을 대형 에너지 저장 시스템(40)이 공급하도록 함으로써 부하관리사업자(20)의 부하관리(LA) 서비스 서버(21)는 전력망 사업자(10)가 요구하는 전력량에 맞추어 전력량을 감소시킬 수 있다.In the large energy storage system 40, the load management (LA) service server 21 of the load management company 20 sums and manages the entire sewage and wastewater treatment plant 30. By supplying the power of 30 to the large energy storage system 40, the load management (LA) service server 21 of the load management service provider 20 may reduce the amount of power according to the amount of power required by the power grid service provider 10. have.
개별 하·폐수 처리장(30)의 에너지 저장설비(32)는 개별 하·폐수 처리장(30)의 부하자원 용량 및 헷징 수단으로 사용된다.The energy storage facilities 32 of the individual sewage and wastewater treatment plants 30 are used as load resource capacities and hedging means of the individual sewage and wastewater treatment plants 30.
부하관리 사업자(20)는 전체 하·폐수 처리장(30)의 부하전력이 전력망 사업자(10)가 요구하는 전력량에 맞추어 감소시킬 수 없는 경우 대형 에너지 저장 시스템(40)에 저장된 전력을 활용하여 이벤트 발생시 전력망 사업자(10)가 요구하는 전력량에 맞추어 감소시킬 수 있다.When the load management company 20 utilizes the power stored in the large energy storage system 40 when the load power of the entire sewage and wastewater treatment plant 30 cannot be reduced according to the amount of power required by the grid operator 10. It can be reduced according to the amount of power required by the grid operator 10.
대형 에너지 저장 시스템(40)은 평상시 전체 하·폐수 처리장(30)의 기본 자원용량에 포함시키지 않고 개별 하·폐수 처리장(30)의 전력량을 취합하여 총괄 전력 자원이 좋지않은 순간을 예측해서 대형 에너지 저장 시스템(40)의 전력량을 전체 하·폐수 처리장(30)의 총괄 전력자원에 포함시킨다. 그럼으로써 이벤트 발생시 전력망 사업자(10)가 요구하는 전력량에 맞추어 감소시킬 수 있도록 한다.The large-scale energy storage system 40 collects the amount of power from the individual sewage and wastewater treatment plant 30 without including it in the basic resource capacity of the entire sewage and wastewater treatment plant 30, and predicts the moment when the total power resource is not good. The amount of power of the storage system 40 is included in the overall power resources of the whole sewage and wastewater treatment plant 30. As a result, when an event occurs, the power grid operator 10 can reduce the amount of power required.
대형 에너지 저장 시스템(40)을 평상시 기본자원으로 활용할 것인지 또는 비상시 포트폴리오 자원으로 활용할 것인지는 개별 하·폐수 처리장(30)의 특성, 국가 예비율의 수준, 부하관리 사업자(20)의 운영 정책 등을 고려하고 여기에 더하여 대형 에너지 저장 시스템(40)의 최대 방전량과 방전회수, 주변환경 및 운영방법 등을 변수로 하여 더 경제적인 경우를 선택한다.Whether to use the large energy storage system 40 as a basic basic resource or portfolio resource in case of emergency, consider the characteristics of the individual sewage and wastewater treatment plant 30, the level of national reserve, the operation policy of the load management operator 20, etc. In addition, a more economical case is selected based on the maximum discharge amount, the number of discharge times, the surrounding environment and the operating method of the large energy storage system 40 as variables.
대형 신재생 에너지 설비(50)는 신재생 에너지를 생산하는 중대형 발전소와 연계하여 전력망 사업자(10)에 등록되어 있는 부하관리사업자(20)가 가져가는 총괄 부하자원용량을 관리하는 방안으로 활용할 수 있다.The large renewable energy facility 50 may be utilized as a method for managing the overall load resource capacity that is taken by the load management company 20 registered in the grid operator 10 in connection with a medium-large power plant that produces renewable energy. .
다수의 하·폐수 처리장(30) 내의 신 재생 에너지 설비(33)는 자체적으로 관리가 가능하고 개별수용가 단위에서 활용할 수 있거나 또는 기본 부하자원용량을 키우는 방법으로 활용이 가능하다. Renewable energy installations 33 in a number of sewage and wastewater treatment plants 30 can be managed by themselves and can be utilized by individual customer units or can be utilized as a way to increase the basic load resource capacity.
그러나 대형 신 재생 에너지 설비(50)는 기본 부하자원용량에 포함시키지 않고 평상시 별도의 목적에 의해 생산하거나, RPS 제도를 통해 판매하는데 사용되고, 전력예비율 비상시 전력부하 이벤트가 발생했을 경우 개별 하·폐수 처리장(30)의 참여가능여부 및 부족자원 등에 대해 대체자원으로 활용하여 최적관리를 하는데 적용된다.However, the large renewable energy facility 50 is not used as a basic load resource capacity but is usually produced for a separate purpose or used for sale through the RPS system, and an individual sewage and wastewater treatment plant in the event of a power load event in case of an electricity reserve ratio emergency occurs. (30) It is applied to optimal management by using as a substitute resource for participation and lack resources.
부하관리사업자(20)가 대형 신 재생 에너지 설비(50)에서 생성되는 전력자원을 수요반응 이벤트 발생시 다수의 하·폐수 처리장(30)에 공급함으로써 페널티를 최소화하기 위한 중요한 방안 될 수 있고 신 재생에너지를 적용하는데 따르는 추가비용 및 회피비용 등은 개별 하·폐수 처리장(30)에서 참여하지 못한 용량만큼 받지 못한 인센티브를 획득하기 위해 활용될 수 있다.The load management company 20 may be an important way to minimize the penalty by supplying the power resources generated in the large renewable energy facility 50 to a number of sewage and wastewater treatment plants 30 when a demand response event occurs, and renewable energy Additional costs and avoidance costs in accordance with the application may be utilized to obtain incentives that are not received by the capacity that did not participate in the individual sewage and wastewater treatment plant (30).
이벤트 발령시 전력부하자원을 줄이는 방법으로는 개별 하·폐수 처리장(30)의 하·폐수 공정설비(31)의 가동 용량을 수동으로 직접 줄이거나 외부에서 통신기기(예를 들면, 스마트 폰 등) 등을 이용하여 하·폐수 처리장(30)의 제어장치에 명령을 내려서 하·폐수 공정설비(31)의 가동 용량을 줄일 수 있고, 또한 오토-수요반응 설비가 설치되어 있는 경우에는 원격으로 제어하거나 사전에 감소시킬 가동용량을 설정하여 자동으로 제어장치가 감소시키도록 할 수 있다.As a method of reducing power source defects at the time of an event, the operating capacity of the sewage / wastewater process facility 31 of the individual sewage / wastewater treatment plant 30 may be manually reduced directly or an external communication device (for example, a smartphone) may be used. It is possible to reduce the operating capacity of the sewage / wastewater process facility 31 by giving a command to the control device of the sewage / wastewater treatment plant 30 using, for example. You can set the operating capacity to be reduced in advance so that the control can be automatically reduced.
