摘　　要：基于尖峰电价机制,引入动态需求价格弹性并分析动态线性价格需求响应,建立了基于尖峰电价并考虑节能减排的机组组合模型,目标函数中加入削减负荷的补偿成本。仿真结果表明,尖峰电价作为考虑需求响应的一种灵活定价机制,能优化机组的启停及出力,还能通过优化价格波动引导需求侧的用电行为和负荷曲线,将高峰时段的部分负荷直接削减,并给予削减负荷一定的补偿,有效地削减了负荷的峰谷差。并综合考虑了节能减排的协调,是协调供需双方在达到供需平衡基础上提高系统节能减排能力的一种有效方式。Critical peak pricing with dynamic elasticity of demand is implemented, and the cost-emission unit commitment model based on critical peak pricing is proposed, Demand cutting cost is introduced in the objective function. Finally, simulation is implemented and the results show the effectiveness of the proposed module. The critical peak pricing as a flexible pricing mechanism can optimize the units status and output. It can also guide the demand side electricity consumption behavior and load curve by optimizing price fluctuation. The penk-valley load can be effectinely reduced by reducing part of the load during the peak period and compensating the load reduction to a certain extent. Considering the coordination of energy and emission, it is an effective way to improve the energy saving and emission reduction of the system based on the balance between supply and demand.
