摘要
针对双轨制新能源参与现货市场,分析了其存在问题与解决思路,采用“单轨制现货市场+管制电价干预机制”思路,提出了新能源参与现货电能量市场的电力交易与结算方式。在现货市场中消除计划与市场分割,所有发用电侧均参与市场竞价与出清,建立了日前机组组合和实时经济调度真正由现货市场决定的资源配置机制,据此构建了双轨制不平衡资金分类与责任认定;通过中长期政府授权差价合约(contracts for differences,CFDs)和二次结算,以金融财务方式转移优发优购平衡责任,有效解决直接参与现货成本回收能力不足的问题,并能够与现行优先优购与价格补贴政策配套协同。IEEE 39节点系统算例验证表明其能够减轻市场扭曲、科学分类与认定优发优购平衡责任,与优发优购政策有效衔接的同时,实现资源配置优化与双轨制不平衡资金分类疏导。
Considering the entry of"dual track"new energy into the electricity spot market and its coordination with the current priority electricity generation and purchase policy,this study adopts a new approach of"single track spot market+regulated electricity price intervention mechanism"to construct a basic framework for new energy to participation in spot electricity market trading and settlement.This framework enables all power generation and consumption sides to participate in spot market bidding,thereby eliminating market segmentation.The responsibility for balancing optimal development and purchasing is transferred through government-authorized price-difference contracts and secondary settlement financial methods.A resource allocation mechanism is established that effectively determines the daily unit combination and real-time economic dispatch through the spot market.Verification using the IEEE 39-node system example demonstrates that this approach can reduce market distortion,scientifically allocate balancing responsibilities,and categorize fund allocation.Furthermore,it effectively aligns with current policies aimed at optimizing resource allocation and categorizing unbalanced funds allocation within the dual track system.
