Recently, East China and Gansu respectively held special meetings to propose policy documents to support the construction of energy storage, frequency modulation and auxiliary service malls.
East China: targeted adjustment of electric energy storage and generator units to participate in AGC, primary frequency regulation related supporting policies and operation procedures.
East China: electric energy storage assisted AGC and primary frequency modulation
In order to promote the healthy development of energy storage power station and solve the related problems found in the investigation of energy storage power station in the previous stage, East China Power Regulatory Bureau organized a meeting on August 26 to discuss the joint participation of energy storage and generator unit in frequency regulation. Shanghai electric power dispatching organization, Waigaoqiao No.3 plant and relevant experts attended the meeting.
Electric energy storage is a good frequency conditioning resource, which can improve the safe and stable operation level of power grid. It can participate in frequency conditioning jointly with traditional thermal power units, improve the frequency regulation performance index of thermal power units, and reduce the cost of AGC and primary frequency regulation audit. Because the technical parameters such as conditioning speed and response time are different between the power storage unit and the generator unit participating in frequency conditioning compared with the traditional thermal power unit, relevant supporting policies and operation procedures need to be adjusted accordingly. The meeting focused on the technical characteristics of the joint participation of electric energy storage and generating units in frequency regulation, analyzed the differences with traditional thermal power units, and exchanged the current and new "two rules" on the applicability of AGC, primary frequency regulation compensation and check terms, AGC master station control strategy, auxiliary service operation data of traditional thermal power units, electric energy storage and generator unit wiring methods and other key issues.
The meeting played an active role, formed relevant policies and skills preparation, and laid the foundation for promoting the joint participation of electric energy storage and generator units in frequency regulation into practical application.
It is understood that in recent years, special research has been carried out in many places in East China to promote energy storage power stations, and this meeting is expected to promote the application of energy storage frequency modulation in East China. Gansu Province, on the other hand, is also discussing and promoting the establishment of rules for FM power auxiliary service stores, and mobilizing enterprises to participate in the activity of FM auxiliary service.
Gansu: cooperate with spot pilot, promote the construction of FM assisted Service Mall.
Gansu: build FM Assistant Service Mall
On the morning of August 21, Gansu Power Regulatory Office organized state grid Gansu Electric Power Company, Gansu Electric Power Trading Center Co., Ltd. and relevant power generation enterprises and energy storage enterprises to hold a meeting in Gansu Province in order to comprehensively summarize the operation experience of Gansu Electric power auxiliary service market, further improve the mechanism of electric power auxiliary service market, cooperate with spot pilot in Gansu Province, and promote the construction of FM auxiliary service market. Special meeting of power assisted Service Mall. Provincial Development and Reform Commission and Provincial Department of industry and information technology were invited to attend the meeting. At the meeting, Gansu Power Regulatory Office introduced the purpose and significance of the construction of FM auxiliary service mall; the provincial power company reported the operation of Gansu Power auxiliary service mall in the first half of the year and the participation of the main body of the provincial mall in the northwest cross provincial auxiliary service mall, and the meeting sought the opinions and suggestions of all parties on the rules of FM auxiliary service Mall (seeking opinions draft). The chief executive of Gansu Power Supervision Office summarized the effectiveness of using marketization to absorb new power in recent two years and the problems still existing. He pointed out that the construction of electric power auxiliary service market is an important action to implement the national electric power system reform spirit and promote the construction of electric power market. The construction of Gansu FM auxiliary service market will further enrich the types of electric power auxiliary service market in Gansu Province, improve the trading mechanism of the market, protect the safe and stable operation of the electric power system, expand the effect of auxiliary service market and mobilize power generation. It is of great significance for enterprises to provide auxiliary services. He asked the main bodies of the shopping malls to further improve their understanding of the marketization of electric power, adhere to the direction of marketization, and jointly promote the development of Gansu Electric Power; secondly, strengthen the discussion on the rules, cooperate with Gansu Power Regulatory Office to do a good job in the rules system and revision, and ensure the safe and stable start of Gansu FM auxiliary service shopping malls.
