Distributed Resource Aggregation and Aggregate Optimization Operation Method of Multi-virtual Power Plant in New Power Distribution Network
With the continuous advancement of the construction of the new power system,the distributed resource ag-gregation and aggregate optimal operation of the distribution network side have become the key technologies for the support of the balance capacity improvement of the power grid.In order to quickly and accurately characterize the power regulation ability of distributed resource aggregate,we first solve the feasible domain of virtual power plant considering the uncertainty of power output.Further,to solve the problem of economic optimal operation of multiple virtual power plants,we design a binary consistency algorithm for active power-reactive power and prove the convergence of the pro-posed algorithm;moreover,we correct the equation based on the feasible domain boundary and binary consistency variable to meet the power and voltage constraints,and obtain the algorithm process of multiple virtual power plant.The example analysis and comparative verification are adopted to verify the feasibility of the framework of the proposed op-timization operation of resource aggregation and aggregation,and its advantages over the traditional consistency algorithm.Through the full use of the active-reactive power regulation capacity of distributed resources,the flexibility of distributed resources to participate in the power grid operation is improved.
