Risk of Renewable Energy Consumption in Spot Market and Preventive Measures

At present, the electricity spot market in China is still at its early stage, lacking market experience and robust market mechanism, and there are still many risks and difficulties for renewable energy to participate in the spot market. This study summarizes and analyses the risks in consuming renewable energy under the operating environment of spot market. Relevant preventive measures from the aspects of price subsidies, ancillary service and cross-provincial spot market are proposed. In addition, by using the electricity market simulation software PLEXOS, this study simulates the participation of renewable energy in cross-provincial spot market with unified optimization clearing method, and verifies the validity of the prosed method.
