基于“三流分离-汇聚”的虚拟电厂架构设计
摘要：随着新能源渗透率的提高，其随机性、间歇性、波动性带来的电力电量平衡与频率稳定问题日益凸显。这些问题仅靠集中式的传统电厂难以应对，电力系统中灵活性资源也应该承担部分电力与电量平衡的责任。虚拟电厂(virtual power plant，VPP)作为分布式灵活性资源聚合调控的载体，可以整体参与市场化的电力市场交易和接受电网的调度，为电力系统实时平衡提供重要支撑。虚拟电厂的发展离不开大量灵活性资源基础、先进通信与调度控制技术、高效盈利模式与完善的市场政策。虚拟电厂的运营可归于能量网络的能量流动、信息网络的信息交互、价值网络的价值传递。为此，基于“能量-信息-价值”的3层网络体系，分析不同类别虚拟电厂的运行模式与控制方案，提出“三流分离-汇聚”的虚拟电厂架构设计思路，为虚拟电厂的设计、建设和运营提供有益的指导。
Abstract:With the increase of new energy penetration, the power balance and frequency stability problems brought by its randomness, intermittency and volatility has become increasingly serious. It is difficult to cope with these problems only by traditional centralized power plants. Flexible resources in the power systems should also bear a part of the responsibility for the balance of power and energy. Virtual power plant (VPP) can aggregate a large number of distributed flexible resources with different characteristics, participate in the electricity markets as a whole and accept the dispatch of the grid, and provide important support for the real-time power balance of the power systems. The development of VPPs should be based on a large number of flexible resources, advanced communication and dispatching/control technologies, and efficient business models and good market policies. The operation of VPPs can be attributed to the energy flow of the energy network, the information interaction of the information network and the value transfer of the value network. Therefore, based on the three-layer network architeciture of “energy-information-value”, the operation modes and control schemes of different types of VPPs were analyzed, and the idea of “three flow separation-convergence” for VPP architecture design was proposed. The findings provide useful guidance for the design, construction and operation of VPPs.
