6 FAQs about Implementation plan for photovoltaic energy storage project

What is the implementation plan for the development of new energy storage?

In January 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan Period, emphasizing the fundamental role of new energy storage technologies in a new power system.

How can storage improve PV production?

The use of storage can change and customize the “shape” of PV production to better match load and peak demand in many power systems, make PV generation more flexible, and facilitate very high levels of PV generation without curtailment. vii

What are the application scenarios for energy storage systems?

There is an extensive range of application scenarios for industrial and commercial energy storage systems, including industrial parks, data centers, communication base stations, government buildings, shopping malls and hospitals.

What are the reactive power requirements for PV power plants?

In conventional power plants with synchronous generators, the reactive power range is normally defined as dynamic, so synchronous generators must continuously adjust their reactive power production or absorption within a power factor range of ±0.95. For PV power plants, the reactive power requirements are not well defined.

Why is accurate estimation important for integrated PV-plus-storage operation?

The accurate estimation of available power in PV plants that happened to be curtailed for any reason is also important for integrated PV-plus-storage operation so that the plant controller can have precise information on the available spinning reserve from PV and can dispatch energy storage accordingly.

Do independent energy storage power stations lease capacity?

Independent energy storage stations lease capacity to wind power, PV, and other new energy stations. Capacity leasing is a stable source of income for owners of independent energy storage power stations. The capacity leased can be seen as energy storage capacity built for new energy projects.
