摘要
构建高效的综合能源系统是解决传统能源产能过剩和可再生能源未充分消纳等问题的重要举措。首先构建了政府监管电价下的区域综合能源系统优化调度模型;以最小化总运行成本为目标,涵盖了电、热、冷、风、光以及储能单元,研究了源荷以及电价具有的不确定性,提出风险评估指标;最后通过算例对综合能源的优化调度及不确定性分析方法加以验证。分析结果表明,综合能源系统有助于促进多能互补,提高清洁能源消纳率。提出的不确定性分析方法能促使决策者对不确定因素造成的风险有更加直观的了解,从而制定经济性更优的调度策略。
Construction of a highly effective integrated energy system(IES)is an important measure for solving problems such as excessive conventional energy capacity and insufficient consumption of renewable energy resources.An optimal scheduling model was established for the regional integrated energy system(RIES)under government regulation of electricity price,aiming at minimal total operating cost and covering electricity,heat,cooling,wind,light and energy storage unit.Uncertainties associated with source load and electricity price were studied,and risk evaluation indicators were proposed.Finally,the approaches for optimal scheduling and uncertainty analysis for the integrated energy system were verified through examples.Analysis results indicated that the integrated energy system could help to enhance multi-energy complement and improve consumption rate of clean energy.The proposed uncertainty analysis method could help decision makers to obtain a more direct perception of risks caused by uncertain factors and formulate a scheduling strategy with better economical efficiency.
