摘要

可信容量形成是虚拟电厂设计中的一项关键任务,是保证虚拟电厂与电网稳定运行的基础。本文基于可信容量的概念,提出了VPP中分布式发电机组的优化配置方法。以预期未服务能量(EENS)作为系统可靠性指标,评价VPP的可信容量。为优化VPP与电网合作运行的效益函数,应用合作博弈论对VPP的DG资源(风能、太阳能和储能)的容量进行配置。分析了EENS的多种场景和可信容量,验证了该方法的有效性。结果表明,该方法可以通过优化配置单个DG机组的容量,成功地获得VPP的可信容量。

Credible capacity forming of a VPP with wind, solar, and storage resources

The credible capacity formation is a critical task in the design of a virtual power plant (VPP) and serves as the foundation for maintaining stability between the VPP and the power grid. In this study, an optimal configuration method for distributed generations (DGs) for units within a VPP is proposed, based on the concept of credible capacity. The expected energy not served (EENS) is used as the system reliability index to evaluate the credible capacity of the VPP. To optimize the benefit function of cooperative operation between the VPP and the power grid, cooperative game theory is applied to configure the capacities of the VPP's DG resources—namely, wind, solar, and storage units. Multiple scenarios of EENS and credible capacity were analysed to validate the effectiveness of the proposed approach. The results demonstrate that the method can successfully achieve credible capacity for a VPP by optimally configuring the capacities of individual DG units.
