Description

Energy integrated management system

The present invention relates to an energy integrated management system, particularly a management system for monitoring auxiliary services of power transactions, and the management system can further perform bidding transactions to obtain a winning period and the auxiliary services that should be performed within the winning period, and Control the charging and discharging schedule of the energy storage device.

Demand response is the use of changes in electricity demand to ensure that the supply of electricity is sufficient to meet electricity consumption. Traditional power systems mainly adjust the output of the power supply end to meet power consumption. However, some generator sets have operational limitations (for example, it takes a certain amount of time to increase or decrease load), and the cost of peak backup units is high. Different from the past method of adjusting from the supply side, demand response is adjusted from the demand side.

A common approach is to lower the price of electricity during peak ionization times to encourage users to use electricity during off-peak hours. This approach must be coordinated with the installation of smart meters. Another approach is demand bidding, which is a way for power companies to manage power demand. During periods of high system load, users are allowed to sell the saved electricity back to the power company, and users bid.

The power company determines the winning bidder on a first-come-first-served basis with the lowest bid. If the winning bidder actually reduces electricity consumption during the period of reducing electricity consumption, he or she will receive a reduction in the electricity bill. This measure gives users more autonomy through self-reported demand response, stimulates the potential to reduce power consumption, and improves the system load pattern, thereby delaying the development of new power supplies or reducing the risk of power curtailment.

Therefore, demand response can flexibly dispatch electricity through the management of the electricity demand side to achieve more efficient energy utilization. It allows electricity market participants to take advantage of the difference in peak and off-peak electricity prices to invest in energy storage, decentralized energy management, Controlling the charging and discharging time of electric vehicles can not only reap benefits, but also reduce power supply pressure.

Taipower has launched the power trading platform and launched "auxiliary services", and operators will bid based on the demand for ancillary services on the "dispatch day" to ensure the stability of the power system. Therefore, in order to cooperate with such a policy and comply with different types of auxiliary services Services, in addition to the need to build an energy storage system for buffering and regulation during power supply and transmission, it also needs to be equipped with:

(1) The transaction meter is a special meter that records the day-to-day transaction information of the ancillary service market. It is used to calculate execution performance, electric energy calculation, etc., and has measurement functions (three-phase voltage, three-phase current, etc.), The power company charges based on the transaction meter; in addition, if you participate in the frequency modulation backup service, you need to have system frequency detection equipment, which measures and outputs a frequency measurement value every 0.1 seconds.

(2) Intelligent electricity meter (AMI), used to calculate energy loss charges.

The trading resources of different ancillary service markets are as follows:

(1) The frequency modulation reserve transfer capacity is calculated based on the transaction information settlement service price recorded by M in the transaction table; the power loss fee is also calculated because there is no need to calculate and charge the basic electricity fee, but the cost is incurred due to the provision of frequency modulation reserve capacity auxiliary services. The power loss suffered by the company shall be calculated based on the company's average power generation and purchase cost and the net power entering and exiting the power grid shall be collected after deducting line losses.

(2) Instant standby capacity is used to respond to unexpected events such as unit tripping and serious imbalances in system supply and demand. Its function is mainly safety capacity standby. The real-time reserve capacity auxiliary service uses the transaction table to calculate the settlement service price of the transaction information recorded by M; however, considering the fact that it does not purchase or sell electricity, it does not include the electricity fee; the power loss fee is based on the fact that it does not need to calculate and charge the basic electricity fee, but due to the implementation Instant backup capacity The power loss caused by ancillary services shall be calculated based on the average power generation and purchase cost and the net power entering and exiting the grid, and shall be collected after deducting line losses. In order to avoid double counting of electricity consumption, settlement and payment will be processed with reference to the records of the smart AMI electricity meter.

(3) Supplementary reserve capacity. If grid-connected energy storage equipment is used to supplement the reserve capacity, there will only be revenue from capacity fees and no electricity fees, and power loss fees must be paid. In order to ensure the rights and interests of the industry and to effectively utilize resources , Grid-connected energy storage equipment should be prioritized for frequency modulation backup capacity or instant backup capacity.

The technical specification requirements for different ancillary service markets are as follows:

(1) Frequency modulation standby transfer capacity. The technical specifications for frequency modulation standby transfer capacity are as follows:

(a) dReg, the trading resource should automatically detect the power system frequency in real time, and perform frequency modulation response in a manner that follows the system frequency changes according to the predetermined operation curve action every second.

(b) sReg is a static one-sided upward response frequency modulation service. When the system frequency drops to the specified frequency, transaction resources should start output within a few seconds and reach 100% of the agreed capacity within 10 seconds to assist the system frequency. Quickly return to the normal range to avoid continued decline in system frequency.

(2) Instant backup capacity is an auxiliary service product activated by receiving dispatch instructions. Trading resources should reach 100% of the agreed capacity within 10 minutes after the dispatch order is issued, and continue to serve for 60 minutes starting from 10 minutes after the dispatch order is issued. The time for calculating the service quality execution rate is calculated from 10 minutes after the dispatch instruction is issued until the continuous service reaches 60 minutes.

(3) Supplementary reserve capacity is an auxiliary service product activated upon receiving instructions and dispatch. After the dispatching instruction is issued, the trading resources should reach 100% of the agreed capacity within 30 minutes and continue to serve for at least 120 minutes.

Therefore, in order to respond to the technical specification requirements of different ancillary service markets, the environmental equipment that reflects it is very important. If there is no corresponding energy storage system for management and control, it is often impossible to meet the technical specification requirements and service quality requirements of different ancillary service markets. Therefore, Efficient energy storage systems are very important.

In addition, a pure energy storage system is not enough for enterprises. If it can simultaneously control the power consumption and power consumption trends of load equipment in the field, it will be able to more effectively regulate the energy storage equipment. Charging and discharging schedule, therefore, this case can use the field's own status and other external factors (trading electricity prices, etc.) as the basis for subscribing the type and time period of auxiliary trading services, so as to achieve the best energy storage mechanism and the best There are two purposes of electricity efficiency and benefit, so the present invention should be an optimal solution.

Among them, the energy integrated management system 4 can calculate the PCSin value based on the current PCS SOC and target frequency, and send it to the PCS. The following instructions give the PCS how much power to output. Take Figure 5 as an example. dReg calculates according to this power curve. , each value is set according to dReg0.25 as shown in Table 1:

The formulas used in the above calculations and their descriptions are as follows:

(1)KW _Adj =KW _Allow *KW _{Adj_coff} , where KW _Adj is the adjustable space allowed by TPC (Taipower Trading Platform) (generally the adjustable space is plus or minus 9%, but it will change according to the actual situation), where KW _Allow is the TPC elasticity adjustment range (as shown in Figure 5, it is 9%, but it will change according to the actual situation). When the loss (weather, dielectric, etc.) cannot be accurately estimated, the elasticity must be limited. interval to avoid affecting SBSPM; where KW _{Adj_coff} is the slope;

(2)PCS _in =(KW _THE +KW _Lost )+(KW _Adj *KW _{SOC_Adj} ), where PCS _in represents how much power the energy integration management system 4 needs to give PCS under instructions; where KW _THE is the theoretical value; and KW _Lost is loss, which occurs both in and out. It will vary depending on the actual situation of the equipment and service execution (generally the loss is estimated to be 1~2%, but it will change according to the actual situation). It is mainly caused by the control equipment (Ex : PCS/TR/cable, etc.) is multiplied by the loss; where KW _{SOC_Adj} is the battery’s adjustable space;

(3) When the frequencies are different, KW _THE , KW _Lost , and KW _{Adj_coff} have different operations respectively. Examples are as follows:

(a) When the power frequency is greater than 60.02, the calculation is as follows: (a1)KW _THE =max((60.02-power frequency)*4.3333,1), where 4.3333 is the fixed slope provided by TPC; (a2)KW _Lost =0 (If it is 0, it represents the free adjustment interval, without considering losses); (a3)KW _{Adj_coff} =Max(0,(100%-8.333333*(power frequency-60.02))).

(b) When the frequency is less than 59.98, the calculation is as follows: (b1)KW _THE =min((59.98-power frequency)*4.3333,-1); (b2)KW _Lost value is corrected based on the empirical value, because the power output The loss will change, so the actual situation will generally be corrected based on empirical values; (b3)KW _{Adj_coff} =Max(0,(100%-8.333333*(59.98-power frequency))).

(c) When the frequency is not greater than 60.02 and not less than 59.98, the calculation is as follows: (c1) KW _THE =0; (c2) KW _Lost =0; (c3) KW _{Adj_coff} =1.

(4) The PCS output will be different if the SOC setting is different (the SOC example is 30~70%, but this range can be changed according to the actual situation), and the different calculations and examples are as follows: (a) When the SOC is greater than 55%, KW _{SOC_Adj} =Min(1,6.66666*(SOC-55%)); If the SOC is greater than 70%, KW _{SOC_Adj} =-1, that is, no charging will be performed; (b) When the SOC is less than 45%, KW _{SOC_Adj} =Max(-1 ,6.66666*(45%-SOC)); If the SOC is less than 30%, KW _{SOC_Adj} =1, that is, charging is carried out; (c) When the SOC is between 45% and 55%, then KW _{SOC_Adj} =0, and it remains uncharged. Not in discharge state.

(5) The above calculation example will be subject to change due to actual conditions or the regulations of TPC (Taipower Trading Platform) or other power trading platforms, so it is only an implementation method, and this case is not limited to this implementation method.
