일반적으로 열병합발전 시스템 또는 열병합발전시스템(Co-Generation System)은 하나의 에너지원으로부터 2종류(열과 전기) 이상의 에너지를 동시에 생산해 낼 수 있는 시스템으로서, 엔진 또는 터빈을 구동, 발전기를 회전시켜 전력을 생산하고, 이때 발생되는 배기가스 또는 냉각수의 배열을 회수하여 급탕이나 공기조화기 등의 열수요처로 공급하는 장치이다.In general, a cogeneration system or a co-generation system (co-generation system) is a system that can produce more than two kinds of energy (heat and electricity) from a single energy source at the same time. It is a device for producing and recovering the exhaust gas or the coolant array generated at this time and supplying it to a heat source such as a hot water supply or an air conditioner.
발전과 배열의 이용을 통해 에너지를 활용하므로 종래 화력발전소의 효율이 35 % 내외인데 반하여, 열병합발전 시스템의 효율은 70 내지 85 % 수준으로 매우 높아, 목동, 분당, 일산 등의 신도시 계획 및 건설시 대형의 집중형 열병합발전시스템이 주요 인프라로 구축된 바 있지만, 최근에는 주민들의 반대 등으로 입지 선정이 여의치 않고 설비 투자비가 많이 드는 집중형 열병합 설비보다는 1 MW 급 이하의 분산형 열병합시스템에 대한 관심이 증대되고 있다. 열병합 시스템은 발전용량에 따라 수십 ~ 수백 kW는 소형 열병합, 수 kW는 초소형 열병합발전 시스템으로 불리며 실제로 전력 열수요가 많은 호텔 등의 대형 빌딩에 분산형 소형 열병합발전시스템이 설치되고 있다. 또한 최근 많은 연구를 통해 전세계적으로 각 세대에서 사용이 가능한 초소형 열병합발전 시스템의 시제품 및 초기 보급사업이 이루어지고 있는 상태이다.Since energy is utilized through the use of power generation and arrangement, the efficiency of a conventional thermal power plant is around 35%, while the efficiency of a cogeneration system is very high, ranging from 70 to 85%, when planning and constructing new cities such as Mokdong, Bundang, and Ilsan. Although a large centralized cogeneration system has been built as a major infrastructure, recently, interest in distributed cogeneration systems of less than 1 MW level is lower than centralized cogeneration systems, which cannot be selected due to the opposition of the residents and costly facility investment. Is increasing. The cogeneration system is called small cogeneration system for tens to hundreds of kW and micro cogeneration system for several kW depending on the power generation capacity. In fact, distributed small cogeneration system is installed in large buildings such as hotels that have high power demand. In recent years, many studies have been conducted on prototypes and early dissemination projects of ultra-small cogeneration systems that can be used in each generation worldwide.
이와 같이 높은 열효율을 갖는 소형 열병합시스템이 많이 보급된다면 에너지 효율 측면에서 많은 잇점을 누릴 수 있으나, 아직까지는 해당 시스템의 구축을 위해서 많은 비용이 소요되고, 운영 비용이 높아 회수기간이 길어지는 문제로 인해 보급이 촉진되기에는 어려운 실정이다.If a large number of small cogeneration system with high thermal efficiency is widely used, it may have many advantages in terms of energy efficiency. However, due to the problem that the cost of building the system is high, and the recovery period is long due to high operating costs. Distribution is difficult to promote.
그러나 태양광에너지나 풍력에너지 등을 이용한 발전설비를 갖춘 가정에서 생산한 전기를 구매해주는 사업과 마찬가지로, 소형 열병합발전시스템에 의해 생산된 열과 전기를 구매해주는 방식으로 인프라가 구축될 수 있다면, 스털링 엔진(Stirling engine), 랭킨 엔진(Rankine engine), 연료전지(Fuel cell), 왕복동식 엔진(Reciprocating Engine), 터빈(Turbine), PVT(photovoltaic thermal) 시스템 등의 기술을 채택한 소형 또는 초소형의 열병합발전 시스템을 건물 또는 공동주택의 각 단지별, 동별, 또는 세대별로 설치하는 것이 좀더 실현 가능해질 것이다.However, if the infrastructure can be built in such a way as to purchase heat and electricity produced by a small cogeneration system, as in the business of purchasing electricity produced in a home equipped with power generation facilities using solar energy or wind energy, the Stirling engine Compact or ultra-compact cogeneration systems using technologies such as the Stirling engine, Rankine engine, Fuel cell, Reciprocating engine, Turbine, and photovoltaic thermal (PVT) systems It will be more feasible to install them by building, building, or household in a building or apartment.
이와 같이 열병합발전 시스템을 수요측 자체 내부에 설치하여 운용하기 위해서는, 열에너지 및 전기에너지 네크워크는 필연적으로 필요하며, 열에너지 및 전기에너지 네트워크는 열에너지 및 전기에너지 공급측이 수요측과 열매체를 수송하는 배관 및 전력을 공급하는 전기 케이블로 연결되어 열에너지 및 전기에너지를 공급하는 시스템이다.Thus, in order to install and operate a cogeneration system inside the demand side itself, a thermal energy and an electric energy network are inevitably required, and in the thermal energy and electrical energy network, a pipe and electric power supplying the demand side and the heat medium are provided by the heat energy and electrical energy supply side. It is a system that supplies heat energy and electric energy by being connected by an electric cable to supply power.
종래의 열에너지 네트워크 시스템 또는 전기에너지 네크워크 시스템은 공급측에서 수요측으로 열에너지 또는 전기에너지를 공급하는 단방향 열/전기 공급 방식이었다.The conventional thermal energy network system or electrical energy network system has been a unidirectional heat / electric supply method of supplying thermal energy or electrical energy from a supply side to a demand side.
구체적으로, 공급측에서 고온의 열매체를 수요측으로 공급하면, 수요측에서는 고온의 열매체로부터 열에너지를 획득하게 된다. 열에너지를 수요측으로 제공하여 저온화된 열매체는 다시 공급측으로 환수되게 된다. 또한, 공급측은 전기 케이블을 통해 전기에너지를 수요측으로 공급한다.Specifically, if the supply side supplies the high temperature heat medium to the demand side, the demand side obtains thermal energy from the high temperature heat medium. By supplying the heat energy to the demand side, the heat-reduced heat medium is returned to the supply side. In addition, the supply side supplies the electric energy to the demand side through the electric cable.
그러나 앞서 언급된 바와 같이 수요측에 설치되어 있는 소형 열병합발전 시스템에서 생산된 열과 전기를 외부의 다른 수요측으로 공급하기 위해서는 종래와는 전혀 다른 방식의 네트워크 시스템이 갖춰져야만 한다. 즉, 종래의 일방향 거래 시스템을 탈피하여 양방향 거래 시스템이 필요한 것이다.However, as mentioned above, in order to supply the heat and electricity produced in the small cogeneration system installed on the demand side to the other demand side, a network system of a completely different method must be provided. In other words, a two-way trading system is needed to overcome the conventional one-way trading system.
양방향 열/전기 거래 시스템은 공급측이 수요측으로 열에너지 및 전기에너지를 공급하는 것은 물론, 수요측에서 자체의 열에너지 및 전기에너지 발생기기를 통해 잉여 열/전기 에너지를 발생시킨 경우, 수요측에서 공급측으로 열 및 전기에너지를 공급 및 판매하는 방식이다. 이러한 방식을 통해 수요측은 각 수요자가 보유한 열병합발전 시스템의 유휴시 또는 잉여열/잉여전기 발생시 열/전기를 생산/공급하여 급변하는 인근의 열/전기 수요에 원거리 공급자에 비해 신속하게 대응이 가능하여 열/전기 공급 만족도를 높일 수 있는 것과 동시에, 열/전기 생산을 통해 이득을 취하여 기기 설치 및 운영비의 회수기간 단축을 기대할 수 있게 된다. 또한 공급자측은 급변하는 수요자측 열/전기 수요를 보다 일정하게 관리할 수 있게 되어 잦은 부하변동을 줄여 안정적인 운전이 가능하게 되며, 또한 열병합발전 설비를 운영하는 경우 최근 동절기에도 급증하고 있는 전기수요에 탄력적으로 대응할 수 있는 운영효과를 겸비하는 장점을 가지게 된다. 이에 따라 이러한 양방향 열/전기 거래 시스템이 구축되는 경우 기존의 수요자-공급자의 관계로 고정되어 있는 관계를 벗어나 수요자측도 필요에 따라 공급자가 될 수 있는 중앙공급 - 분산열원 결합 기반의 열/전기 에너지 네트워크 시스템을 구현할 수 있다.The bidirectional thermal / electrical trading system not only supplies heat energy and electric energy to the demand side, but also generates excess heat / electric energy through its own heat and electric energy generating equipment on the demand side. And a method of supplying and selling electrical energy. In this way, the demand side can produce and supply heat / electricity when the cogeneration system owned by each consumer is idle or when surplus heat / surplus electricity is generated, so that the demand side can respond quickly to the rapidly changing neighboring heat / electricity demands compared to the remote suppliers. In addition to improving thermal / electrical supply satisfaction, the company will benefit from thermal / electrical production and expect a shorter payback period for equipment installation and operating costs. In addition, the supplier side can manage the rapidly changing consumer's heat / electricity demand more consistently, thereby reducing the frequent load fluctuations, and enabling stable operation.In addition, when the cogeneration plant operates, it is resilient to the recent increase in electricity demand during the winter season. It will have the advantage of having operational effects that can be coped with. Accordingly, when such a bidirectional thermal / electrical trading system is established, the central supply-distributed heat source combination-based thermal / electric energy network that can be a supplier as needed, out of the fixed relationship of the existing consumer-supplier relationship. You can implement the system.
이러한 양방향 열/전기 거래는 공급측과 수요측 간에도 이루어질 수 있을 뿐만 아니라, 서로 다른 수요측 간에도 이루어질 수 있다.Such bidirectional thermal / electricity transactions can be made not only between the supply side and the demand side, but also between different demand sides.
따라서, 열병합발전 시스템 운전에 따른 잉여열 발생 또는 열판매수요에 따른 열생산시에 따른 열거래 시 공급측과 수요측의 관계가 상황에 따라 가변 될 수 있으므로 이를 조절할 수 있는 구조 및 이때 발생하는 구매 혹은 판매 시 발생하는 열에너지의 유량을 정확히 측정할 필요가 있다.Therefore, the relationship between the supply side and the demand side may vary depending on the situation in the case of excess heat generation due to the operation of the cogeneration system or heat production according to the heat sales demand, so that the structure and the purchase or It is necessary to accurately measure the flow rate of thermal energy generated at the time of sale.
그러나 종래 기술에 있어서, 전기의 경우 현재에도 전세계적으로 신재생 발전원 또는 열병합발전 시스템을 보유한 세대 또는 건물의 경우 양방향으로 계측이 가능한 양방향 전력계를 이용하여 전력회사에 판매하는 것이 가능하다. 하지만 열에너지의 경우는 수요처에서 발생한 열을 양방향으로 제어, 판매할 수 있는 네트워크 배관구조, 측정방법 및 제어방법이 전무하여 열병합발전 시스템이 전기 수요에 대응하기 위해 발전하는 경우 같이 발생하는 열은 버려질 수 밖에 없도록 구성되어 있다. 더욱이 종래 기술에 따른 열에너지 네트워크 시스템은 열거래 시 발생하는 열에너지의 유량을 일방향 흐름에 관해서만 측정할 수 있을 뿐, 양방향 모두에 관해서 측정할 수 없는 문제점이 있다.However, in the prior art, it is possible to sell electricity to a power company using a bi-directional power meter that can measure in both directions in the case of electricity, in the case of a generation or a building having a renewable energy source or a cogeneration system worldwide. However, in the case of thermal energy, there is no network piping structure, measurement method, and control method that can control and sell heat generated at the demand source in both directions. Therefore, the heat generated when the cogeneration system generates power to meet the demand of electricity will be discarded. It is configured to be forced. Moreover, the thermal energy network system according to the prior art can measure the flow rate of thermal energy generated during heat transactions only in one-way flow, and cannot measure in both directions.
따라서, 열에너지 공급측, 수요측 및 또 다른 수요측 간의 열에너지 네크워크 시스템에 대한 구체적인 해결방안이 필요한 실정이다.Therefore, there is a need for a concrete solution for the thermal energy network system between the heat energy supply side, demand side, and another demand side.
