In addition, develop long-duration energy storage technologies such as compressed air to enhance technological economic viability and system energy conversion efficiency; moderately advance the layout of hydrogen storage and other ultra-long-duration energy storage technologies, encourage the development of various types of hybrid energy storage technologies based on application needs, and support basic research on forward-looking technologies such as new system batteries and thermal storage.

The project construction plan, main technical indicators, and key equipment selection should comply with relevant regulations, standards, and specifications for new energy storage power stations.The Southern Energy Supervision Bureau issued the revised version of the "Implementation Rules for the Operation and Auxiliary Service Management of New Energy Storage Grid Connection in the Southern Region" (February 14)On February 14, the Southern Energy Supervision Bureau issued the revised version of the "Implementation Rules for the Operation and Auxiliary Service Management of New Energy Storage Grid Connection in the Southern Region," which mentions encouraging power generation companies, electricity sales companies, power users, energy storage companies, or other market entities to invest in the construction of energy storage facilities, promoting new energy storage to provide auxiliary services such as frequency modulation, peak shaving, voltage regulation, and black start for the operation of the power system. Relevant local government departments and energy regulatory agencies should refine regulatory measures according to their respective responsibilities, strengthen supervision of independent energy storage scheduling operations, ensure that socially invested energy storage power stations receive fair scheduling, and have equal rights and comparable utilization rates.

02 This modification divides primary frequency modulation compensation into small frequency disturbance and large frequency disturbance. The primary frequency modulation input rate and monthly qualification rate of independent energy storage power stations both reach

Independent energy storage stations should have primary frequency modulation capabilities, with performance indicators including control dead zone, frequency modulation limit, response time, adjustment time, etc. The relevant technical requirement for the primary frequency modulation dead zone is±0.033~0.05Hz.The adjustment amount of active power for primary frequency modulation is generally not limited, and if necessary, the limit should not be less than 20% of the rated power.The adjustment rate for primary frequency modulation should be set at 0.5%~3%.The lag time should not exceed 1 second, and the adjustment time should not exceed 4 seconds.The accuracy of active power adjustment should not exceed ±1% of the rated output.The primary frequency modulation function must not conflict with the AGC function.

Germany cancels negative electricity price subsidies

1. Cancel the photovoltaic grid connection subsidy during negative electricity price periods:

During negative electricity price periods, photovoltaic system operators will not be able to receive subsidies for feeding electricity into the grid. This measure aims to alleviate the financial pressure on the federal renewable energy EEG account and promote more efficient management of grid supply and consumption.

2. Extension of subsidy period:

Although subsidies during negative electricity price periods are canceled, the subsidy period will be extended accordingly to ensure that operators do not have concerns about profitability due to losses during negative electricity price periods.

3. Limitations on photovoltaic system generation:

The generation of newly installed photovoltaic systems (with a power greater than 7kW) will be limited to a maximum of 60% of the system's maximum power.

These systems need to be equipped with intelligent metering systems (iMSys) for power management and optimization.

If there is no energy storage device, the grid connection power of these systems will be limited.

4. Compensation mechanism:

Voluntary participating system operators can receive a compensation of 0.6 euro cents per kilowatt-hour to mitigate the impact of policy adjustments.

5. Encouragement of energy storage systems:

Photovoltaic systems equipped with energy storage systems are not affected by grid connection power limitations and can flexibly adjust their generation.
