This paper deals with the internal dispatch policy for Hybrid Power Stations (HPS) consisting of (RES) based generation and storage facilities, operating in isolated island power systems in a coordinated manner to provide dispatchable power.
At present, more than 20 provinces and cities in China have issued policies for the deployment of new energy storage. After energy storage is configured, how to dispatch and operate energy storage, how to participate in the market, and how to channel costs have become the primary issues which plague new energy companies and investors.
Based on the above analysis, as the first comprehensive policy document for the energy storage industry during the ‘14th Five-Year Plan’ period, the ‘Guidance’ provided reassurance for the development of the industry.

Main objective of the internal dispatch policy is to maximize the operating profit of the HPS-O by optimally exploiting available RES energy, while avoiding deviations from the DOs issued by the SO, via proper coordination of the generation and storage facilities of the HPS.
As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
