考虑清洁能源参与的跨区域能源配置优化模型

分别以区域发电成本最优、区域碳排放最优以及综合效益最优为目标,结合区域能源优化中涉及的经济效率、碳排放以及输电约束等问题,构建了含清洁能源的跨区域发电计划优化模型.利用GAMS软件进行模拟分析,结果表明模型能在一定程度上优化区域间的发电成本和环境成本;对比清洁能源参与、不参与区域能源优化的结果可知:清洁能源在优化中的贡献度明显高于化石能源;区域间碳排放价格的差异将影响清洁能源与化石能源所实现的能源置换效益.

An Optimization Model for Inter-regional Energy Allocation under Consideration of Clean Energy

Three optimization models of inter-regional generation scheduling including clean energy generation, taking minimum regional generation cost, and minimum regional carbon emission cost and minimum comprehensive cost as objective functions respectively, were established, and the models considered the issues of economic efficiency, carbon emission, and transmission constraints. The simulation analysis using general algebraic modeling system(GAMS) shows that, (a) the model presented can optimize the inter-regional generation cost and environmental cost to a certain extent; (b) clean energy plays a more important role in the optimization of inter-regional energy allocation than fossil fuel energy by comparing the results of inter-regional energy allocation optimization with and without clean energy generation; and (c) the difference of carbon emission prices in regions will influence the benefit achieved by the energy replacement of clean energy and fossil fuel energy.
