Multi-Virtual Power Plant Distributed Transaction Strategy Considering Source Load Uncertainty

To solve the problem of distributed transaction between multi-virtual power plant(VPP) considering the uncertainty of renewable energy and user load, a multi-VPPs distributed transaction model considering the uncertainty of source load is proposed. First, a typical model of a single virtual power plant is constructed. Secondly, in view of the gap between renewable energy output and load size, the conditional value at risk theory(CVaR) is used to quantify the risk caused by its uncertainty factors. Finally, a multi-VPP distributed transaction model considering the uncertainty of source load is constructed and solved by alternate direction multiplier method(ADMM).The numerical results show that this method can effectively consider the interests of each VPP and improve the transaction efficiency and cost.
