Optimal Scheduling Strategy Considering Linkage Uncertainty of Distributed Resources in Virtual Power Plant
The linkage uncertainty among distributed resources in a virtual power plant (VPP) poses significant challenges to the accuracy of the response of the VPP to power grid scheduling. To address this issue
this paper proposes an optimal scheduling strategy considering the linkage uncertainty of distributed resources in a VPP
aiming to enhance the economic efficiency of VPP scheduling and the accuracy of response. Firstly
this paper portrays the linkage uncertainty of distributed resource power variations through seasonal trend decomposition and cross-correlation analysis
and constructs a linkage matrix. Secondly
a comprehensive assessment method is proposed. This method optimizes the recovery process of distributed resources after responding to scheduling to minimize the economic cost of scheduling
which holistically considers the economics and linkage uncertainty. Then
a dynamic scheduling strategy based on the Gaussian Copula function is introduced. By establishing a correlation model among resources
this strategy dynamically adjusts the scheduling process to improve both accuracy and economic efficiency. Finally
the real data from 247 charging stations in Shenzhen
China
are used for simulation validation. Simulation results demonstrate that
compared with existing methods
the proposed scheduling strategy of distributed resources can reduce the costs by 10.09%.
