考虑需求侧响应的风光储工业园区经济调度与实时控制OA

The high proportion of renewable energy system is an inevitable choice to achieve the dual carbon target,but the uncertainty of wind and solar output will cause serious wind and light abandonment.With the deepening reform of the electricity market,the demand-side response has also attracted much attention.In view of the above problems,taken the wind-solar-storage industrial park as the research object,combined with the operation mechanism of Guangdong power spot market,a multi-time scale joint optimization operation method was proposed.In the day-ahead stage,considering the demand-side response,an economic dispatch model with the minimum daily operation cost of the park as the target was established,and the 24 hours power plan curve of the spot day-ahead market was obtained.In the real-time stage,the control strategy of using the hybrid energy storage system to stabilize the planned power deviation of the wind-solar-storage industrial park was proposed.The simulation results show that this method can improve the utilization rate of wind and solar energy and significantly improve the economic operation level of the park.On a typical sunny and windy day,the total cost of the park's day-ahead operation decreased by 37.12%,and the assessment power decreased by 93.5%.On the typical day of rainy days and less wind,the total cost of the park's day-ahead operation decreased by 10.1%,and the assessment power decreased by 99.9%.The qualified rate of the control index is significantly improved,and the planned power deviation is effectively improved.
