Dynamic Aggregation Response Strategy of Adjustable Resources of Virtual Power Plants in Power Grid Balance Adjustment Scenario

To guarantee the reliability and efficiency of power grid operation, it has become an inevitable trend for virtual power plants (VPP) to provide balance adjustment services for the power grid through the coordinated operation of multiple internal resources. When VPP continuously participates in power grid balance adjustment, it must provide stable available capacity not to bring additional volatility to the power grid. It is challenging to meet the above requirements by only relying on one or several types of adjustable resource clusters to perform disorderly responses. Therefore, this paper proposes a dynamic aggregation response strategy by establishing a state priority queue within the response cluster. The strategy is tested in the actual situation, which proves its effectiveness.
