Under the premise of meeting the safe operation of power system and equipment, the distribution network with access to distributed photovoltaic power generation is allowed to transmit electricity to the transmission network. In terms of grid-connected mode, natural person household use, non-natural person household use distributed photovoltaic can choose full Internet access, all spontaneous self-use or spontaneous self-use surplus electricity network mode; general industrial and commercial distributed photovoltaic can choose all spontaneous self-use or spontaneous self-use surplus electricity network mode;Large-scale industrial and commercial distributed photovoltaic must choose all spontaneous self-use modeThe main body of the project investment shall realize the spontaneous self-use of all power generation by configuring the anti-reverse flow device.

 03 Guangdong to try out electricity compensation for independent energy storage

On October 10, the Guangdong Provincial Development and Reform Commission issuedNotice of Guangdong Provincial Development and Reform Commission on the Trial Implementation of Electricity Charge Compensation Mechanism for Independent Energy Storage Power Stations in Guangdong Province (Draft for Comments),The amount of electricity compensation available for an independent energy storage power station is determined by the compensation standard and the monthly available maximum capacity, whereThe annual compensation standard is unified at 100 yuan/kilowatt (including tax)。

Independent energy storage power stations can be compensated for electricity charges if they meet one of the following two conditions: one is to obtain a new energy storage pilot demonstration project recognized by the national or provincial energy authorities; The second is an independent energy storage project that is included in the annual plan from 2023 to 2025 and will enter commercial operation before the end of 2025. Independent energy storage projects implement annual construction plan management.The power grid enterprises pay the amount of electricity compensation to the independent energy storage power station on a monthly basis, and the payment funds are borne by the peak increase in electricity charges in Guangdong Province.

 04 Guangdong Releases New Fire Protection Regulations for Energy Storage Power Stations

On September 30, the Guangdong Provincial Fire Rescue Corps releasedTechnical Standard for Fire Safety of Electrochemical Energy Storage Power Station (Draft)More detailed technical specifications have been made for the fire safety of energy storage power stations. After the official release of the technical standard, it will become one of the necessary documents for investment, construction and operation of fixed electrochemical energy storage power stations with rated power of 500kW and rated energy of 500kWh and above in Guangdong Province.

The technical standard makes clear specifications for the response time (≤ 2s) and time limit for extinguishing open fire (≤ 15s) of the automatic fire extinguishing system of the prefabricated cabin lithium ion battery energy storage power station, the time limit for starting the battery module fire extinguishing device to release the fire extinguishing medium (≤ 1s), the time limit for extinguishing the budding fire (≤ 1s), the activation temperature (120 ℃-170 ℃), etc; the fire resistance limit of the partition wall around the battery room building of the factory-type energy storage power station has also made technical requirements.

 05 Implementation Measures of Yunnan Electric Power Market Supervision Released

On October 11, the Yunnan Regulatory Office of the National Energy Administration issuedMeasures for the Implementation of Yunnan Electricity Market SupervisionYunnan power market supervision object is to participate in the province and cross-provincial cross-regional power medium-and long-term market, in stock market, auxiliary service market, capacity market and other types of power market members. Power market members include power trading entities, power market operators and power grid enterprises that provide transmission and distribution services.

Power trading entities include power generation enterprises, power sales enterprises, power users, energy storage enterprises, virtual power plants, load aggregators, etc. When a power grid enterprise implements an agent purchase of electricity in accordance with the relevant provisions of the State, it may be regarded as the subject of electricity trading.

 06 Hunan Releases New Regulations for New Energy Storage Project Management

Issued by Hunan Provincial Development and Reform CommissionNotice on Standardizing the Management of New Energy Storage Projects, yes.PowerSide energy storage, grid side energy storage, user side energy storage in the filing, construction, grid, operation and maintenance have made detailed provisions.

Hunan Province mainly develops new energy storage on the power grid side and the user side. New energy storage projects needStrengthen the Management of Equipment Supervision and Arrival Sampling Inspection. Before the project is put into operation, it shall apply for fire control acceptance and record of the construction project according to law. In principle, user-side energy storage projects shall not use power ladder utilization batteries. The scale of the user-side energy storage project shall not exceed the user's maximum electricity load or telegraph installation capacity. The user-side energy storage and distributed photovoltaic within the same user shall be equipped with separate metering devices. Encourage new energy storage projects with grid-connected voltage levels of 380 volts and below to give priority to participating in market-oriented transactions in aggregate mode.

 07 Hunan intends to pilot a new type of energy storage as a price receiver to participate in in stock market scheduling calls.

On September 30, the Hunan Provincial Development and Reform Commission issued the "Notice on Publicly Soliciting Opinions on Hunan Electric Power in stock Market Rules and the Third Settlement Trial Operation Work Plan", and issued the "Hunan Electric Power in stock Market Transaction Implementation Rules (Trial Operation 3.0 Edition) (Draft for Solicitation of Comments)", "Hunan Electric Power in stock Market Settlement Implementation Rules (Trial Operation 3.0 Edition) (Draft for Solicitation of Comments)", "Hunan Electric Power in stock Three documents, the Work Plan for the Third Settlement Trial Operation of the Market (Draft for Solicitation of Comments).

The user-side business entities involved in in stock transactions include power users and power sales companies. Grid-connected capacity not less5 MW/10 MWh Dispatch Call New Energy StorageYou can choose whether to participate in in stock transactions.; Meet the market access conditionsVirtual power plants and distributed power supplies can participate in in stock transactions.。

In terms of market convergence mechanisms, the document states that during the operation of the in stock market,No longer carry out separate transactions of peak shaving auxiliary services in the province..
