省间电力现货交易机制设计与探索

随着电力市场化改革的逐渐深入和新能源渗透率的快速提升,我国电源结构和电力供需情况正在发生深刻变化,从而对新能源消纳和省间余缺互济提出了更高要求。目前省间余缺互济市场化机制缺失,亟需开展省间电力现货交易,通过市场化手段开展省间余缺互济,促进可再生能源大范围消纳。文章在跨区域省间富余可再生能源现货交易实践基础上,结合电网实际运行需要,进一步扩大交易范围、丰富交易主体、完善交易机制,建立了省间电力现货交易整体框架,设计了市场衔接、竞价出清、多级调度协同运作等关键机制,提出了市场出清模型。最后通过算例分析验证了上述机制的可行性和有效性。可为开展省间电力现货交易提供切实可行的实施路径和技术方案。

Design and Exploration of Inter-provincial Power Spot Trading Mechanism

With the gradual deepening of market-oriented power sector reform and the rapid increase of new energy penetration,profound changes are taking place in China's power structure and power supply and demand,and higher requirements need to be put forward for new energy consumption and shortage/surplus coordination between provincial supplies.At present,as the market-oriented mechanism for the shortage/surplus coordination between provinces has not yet been established,it is urgent to realize the spot power trading among provinces to coordinate the power shortage and surplus through the market-oriented means in order to promote the large-scale consumption of renewable energy.This study,based on the practice of cross-regional inter-provincial spot trading of surplus renewable energy and taking into consideration the actual operation needs of power grids,establishes the overall framework of the inter-provincial power spot trading by further expanding the trading scope,enriching the trading subjects and improving the trading mechanism.It puts forward the research on the market clearing model by designing the key mechanisms such as market connection,competitive price clearing and multi-level dispatching collaborative operation.Finally,the feasibility and effectiveness of the above mechanisms are verified through calculation cases,offering a practical implementation path and technical scheme for the inter-provincial spot trading.
