摘　　要：高比例新能源接入对电力系统容量充裕性及惯量水平影响较大,系统必须配置充足的容量应对新能源出力的不确定性及系统低惯量问题,并充分接纳新能源发电。传统确定性容量优化仅考虑负荷且忽视系统惯量需求,在大规模风光接入的背景下难以保证电力系统安全经济运行,针对此问题,本文提出一种计及惯量需求与碳交易机制的两阶段鲁棒容量优化配置模型,模型考虑频率安全约束以量化惯量需求,并引入碳交易机制与价格型需求侧响应,起到优化电源结构、提升经济性的作用。模型充分考虑风光荷的不确定性和波动性,采用区间概率法构建不确定集,以缓解模型保守度,能够最小化系统在最恶劣情况下的综合成本。最后,通过算例仿真分析验证了所提模型的可行性。The high proportion of new energy access has a large impact on the capacity adequacy and inertia level of the power system,and the system must allocate sufficient capacity to cope with the uncertainty of new energy output and the low inertia problem of the system,as well as to fully accept new energy generation.The traditional deterministic capacity optimization only considers the load and ignores the system inertia demand,which makes it difficult to ensure the safe and economic operation of the power system in the context of large-scale wind access.To address this issue,this paper proposes a two-phase robust capacity optimization model taking into account the inertia demand and the carbon trading mechanism,which takes into account the frequency security constraints to quantify the inertia demand and introduces the carbon trading mechanism and the price-type demand-side response,which optimizes the power supply structure and improves the economy.The model takes into account the frequency safety constraint to quantify the inertia demand,and introduces the carbon trading mechanism and price-based demand-side response to optimize the power structure and improve the economy.The model fully considers the uncertainty and volatility of wind and light loads,and adopts the interval probability method to construct the uncertainty set to alleviate the model conservatism,that will minimize the comprehensive cost of the system in the worst case.Finally,the feasibility of the proposed model is verified by arithmetic simulation analysis.
