JOINT MARKET CLEARING MODEL CONSIDERING PARTICIPATION OF NEW ENERGY AND ENERGY STORAGE IN FREQUENCY MODULATION
With the increasing penetration rate of new energy and the integration of more and more energy storage devices into the power grid,the current frequency modulation market mechanism can no longer adapt to the actual situation of the power system.Based on this situation,a joint clearance model of frequency modulation auxiliary service market and electricity energy market involving wind turbine generators,photovoltaic panels,independent energy storage devices and conventional thermal power units is built.In the model,the analytic hierarchy process(AHP)is used to optimize the weight of frequency modulation performance indicators,which reduces the frequency modulation pressure of the power system after the participation of new energy and independent energy storage devices in the grid frequency modulation,and further improves the absorption of new energy.The example analysis shows that the introduction of new energy units with high permeability and independent energy storage devices to participate in the power market can not only reduce the bidding of thermal power units with poor frequency modulation performance,reduce the phenomenon of wind and light abandonment,but also reduce the cost of purchasing frequency modulation service for operators.
