摘　　要：虚拟电厂(virtual power plants,VPP)作为新兴市场主体,逐步在多市场交易品种中获得准入地位,通过聚合灵活分布式资源响应系统调度指令、执行交易结果,为新型电力系统拓展了可调节资源。现阶段,虚拟电厂处于以参与辅助服务市场为主、参与能量市场为辅的业务形态。随着高比例新能源的渗透,虚拟电厂向现货市场过渡将成为重要业务拓展方向。研究了适应虚拟电厂参与的现货市场出清模型,允许虚拟电厂通过引入灵活申报方式反应自身的灵活调节特性,用以提高电力市场交易供需双方匹配率;同时基于不同交易模型出清结果的对比分析,建立了虚拟电厂灵活性的溢价评估方法,实现了虚拟电厂定价体系由能量定价向“能量+灵活性”定价模式转变,从而提高了灵活资源虚拟电厂在电力市场中的竞争力和价值认证。As emerging market entities, the virtual power plants have gradually gained their access statuses in the multi-market trading varieties. They have expanded the adjustable resources for the new power systems by aggregating the flexible distributed resources in response to the system dispatching instructions and the executing transaction results.At present, the virtual power plants are in a business form of trading in the auxiliary service market supplemented by taking part in the energy market. With the penetration of a high proportion of renewable energy, the transition of virtual power plants to the spot market will become an important business development direction. This paper studies the spot market clearing model adapted to the participation of the virtual power plants, allowing the virtual power plants to reflect their own flexible regulatable characteristics by introducing the flexible bidding ways to improve the matching rate of supply and demand in the electricity market transactions. At the same time,this paper proposes a premium evaluation for the flexibility of virtual power plants based on the comparison and analysis of the clearing results of different transaction models, which realizes the pricing system transformation from energy only to "energy + flexibility" two-part tariff and improves the competitiveness and value certification of the virtual power plants in the electricity market.
