摘　　要：包含大规模随机机组的虚拟电厂(VPP)在运行过程中,会由于随机机组出力不确定性产生系统运行风险及收益损失风险。针对该问题,文中基于多代理系统(MAS)的分层控制特点,构建了整合条件风险价值(CVaR)的两阶段双层分解(BLDP)模型。选取多目标规划(MOP)模型与文中构建的BLDP模型进行对比,以验证BLDP模型的有效性。结果显示,BLDP模型求解条件下,各VPP既参与电力市场交易又进行相互交易时系统的出力更稳定,具有更高的系统收益,且受风险水平变化的影响也更小。在不同的交易机制下,BLDP模型的求解结果较MOP模型具有更高的系统收益率。当各VPP独立参与电力市场而不进行相互交易时,BLDP模型的求解结果较MOP模型高103%;当VPP同时参与相互交易及电力市场交易时,BLDP模型的求解结果较MOP模型高147%。模拟结果验证了文中构建的BLDP模型在不同风险条件下的可靠性。There may exist system operational risks and the risks of losing the revenue because of the generating uncertainty of the stochastic units during the operational process of the virtual power plant(VPP),which contains multiple large scale stochastic units.To solve these problems existing in VPP,a two-stage bi-level decentralized planning(BLDP)model incorporating the conditional value-at-risk(CVaR)based on the characteristics of hierarchical control in the multi-agent system is built.Multi objective programming(MOP)model is selected and compared with the BLDP model constructed in this paper to verify the effectiveness of the BLDP model.It indicates that when VPP participates in the market independently and trades with other VPPs under the BLDP scenario,the system will achieve higher profits and be affected less by the risk levels.Meanwhile,the system can get higher yield rate under BLDP scenario than that under MOP scenario under different trading mechanisms,when VPP participates the power market independently without mutual dealing,results obtained under the BLDP scenario are 103%higher than that under the MOP scenario,while when it takes part in both the market and mutual dealing,the results under the BLDP scenario are 147%higher than that under the MOP scenario.The results have demonstrated the availability of the proposed model under different risk levels.
