Peaking Shaving Benefits Comparison of Various Grid-side Energy Storage Facilities in High-proportion New Energy Systems
A comprehensive benefits assessment is critical for large-scale development of the energy storage business.The paper conducts the benefits assessment of the energy storage on the grid side of a high proportion of new energy systems,calculates the capacity and electricity benefits of pumped storage,compressed air,and electrochemical energy storage through full time 8760h production simulation under the constraint of maintaining the reliability of system power supply,and considers the operating strategies of various energy storage power stations.In the simulation process,it calculates the system operation status of 8760 hours throughout the year on a weekly scale and takes into account such factors as the operational efficiency of energy storage power plants,unit start&stop,and cross day regulation to avoid the problem of distorted energy storage capacity and electricity efficiency evaluation caused by the inability of typical daily production simulation to simulate cross day regulation of energy storage.The paper,finally,analyzes the effects of various energy storages on decreasing thermal power installations and reducing the rate of new energy abandonment by taking the actual high proportion of new energy systems in Northwest China as the research object and the research results can be used for the grid-side energy storage power plants of high proportion new energy systems in China as a reference.
