Economic Analysis of the Charging-Discharging-Storage Integrated Station Based on Demand Response

The constructions of energy corollary facilities electric vehicle (EV) charging-discharging-storage integrated station is a Platform that integrates the advantages of charging stations, power stations and power storage stations. In the power market, the operating economic benefits of this platform are the core factor of its survival and development. As a service provider for Power Network and electric vehicles (EV), different Operation mode can be taken and meet the requirement of both. The response on the demand side described in this passage is that the grid guides the integrated station to adjust the operation mode by the market price. In opinion of economics, this paper calculates the economic benefit of the integration station under the three modes of operation of frequency modulation, spinning reserve service and Peak-Load Regulation, Comparison and analysis of three groups were carried out. The results showed that the economic benefit of charge-discharge-storage integrated station provided Peak-Load Regulation is the best, and Profit from providing frequency modulation (FM) is greater than Profit from providing spinning reserve service. Integrated station participates in ancillary services in electricity market is a feasibility development direction for providers of electric vehicle service in the future.
