To meet the challenge of the “three highs and one limit” of the Shenzhen power grid operation, the virtual power plant (VPP) is proposed to effectively utilize the flexible distributed energy resources (DERs) to optimize the operation scheme of the distribution network. Firstly, based on the investigation of the available and controllable DERs of the Shenzhen power grid, typical application scenarios representing the characteristics of the Shenzhen power grid are formulated. Secondly, the framework and roadmap of the typical regional VPP in Shenzhen are proposed. Thirdly, a coordinated optimal scheduling strategy for the VPP is proposed to solve the voltage issues caused by overload or other reasons in Shenzhen's distribution network. Finally, a case study is carried out on the distribution networks using that of the Shenzhen Potevio New Energy company, Shenzhen Bay Science and Technology Eco-Park are connected. The results show that the voltage level of the distribution network can be improved by the proposed optimal control strategy of the VPP, and verify the effectiveness of the proposed VPP scheme and the benefits of the VPP for the Shenzhen power grid operation.

深圳市虚拟电厂实施方案

为应对深圳电网运行“三高一限”的挑战，提出虚拟电厂（VPP），有效利用柔性分布式能源（DER）优化配电网运行方案。首先，基于对深圳电网可用可控分布式能源的调查，制定了代表深圳电网特点的典型应用场景。其次，提出了深圳典型区域VPP的框架和路线图。第三，针对深圳配电网因过载或其他原因引起的电压问题，提出了VPP协调优化调度策略。最后，以深圳普天新能源公司配电网与深圳湾科技生态园互联为例进行了案例研究。结果表明，提出的VPP优化控制策略可以提高配网电压水平，验证了提出的VPP方案的有效性和VPP对深圳电网运行的效益。
