Energy storage grid peak load auxiliary service

What are the administrative measures for electric power auxiliary services?

To standardize the management of electric power AS, the Administrative Measures for Electric Power Auxiliary Services is issued, adding technical guidance and management requirements for new energy, new energy storage, and demand-side management .

Which power system should exceed the maximum load?

In an electrical power system that consists of thermal power plants, CSP plants, and PV power, the installed capacity of thermal power plus the credible capacity of CSP and PV power should exceed the maximum load.

Which auxiliary service market has a higher scheduling priority?

Research shown that in auxiliary service markets, the FR market has a lower capacity demand threshold, but the return on investment is considerable. Therefore, it often has a higher scheduling priority . In FR markets, Bahloul et al. adopted a hybrid power sharing method to optimize the fast frequency response performance of HESS.

How AA-CAES Auxiliary Service works?

PS auxiliary service In response to the demand for the seasonal peak load reduction, ESS is combined with thermal power units for deep PS. The participation of AA-CAES in PS can alleviate the supply-demand imbalance and improve the economical operation of the system.

What is hybrid energy storage?

Hybrid energy storage (HESS) integrates power and energy advantages, which can effectively control the power over-limit, promote the consumption of wind power and photovoltaic, and relieve the PS pressure of conventional generators [9, 10].

Is peak shaving based on unit load rate & peak shaving contribution (PSC)?

Two mechanisms respectively based on the unit load rate (ULR) and peak shaving contribution (PSC) are proposed and examined, and the bidding range and quotation range for peak shaving of CSP under the two mechanisms are suggested according to the cost of the peak shaving capacity of CSP.
