荷源联合调峰运行方案的电力节能评估研究

针对当前大规模风电远距离外送造成输电网网损激增和调峰能力不足的矛盾,提出将高载能负荷参与常规电源调峰,在风电就地消纳的同时实现电力节能。在深入分析高载能负荷的调节特性和对电网调峰影响的基础上,从电网、电源和高载能负荷三个方面提出了表征电力节能的指标并进行量化。最后基于综合模糊评价法对荷源联合调峰运行方案进行电力节能综合评估。仿真结果表明,该指标体系及方法在荷源联合调峰运行方案电力节能评估方面是有效可行的。...

Summary:针对当前大规模风电远距离外送造成输电网网损激增和调峰能力不足的矛盾,提出将高载能负荷参与常规电源调峰,在风电就地消纳的同时实现电力节能。在深入分析高载能负荷的调节特性和对电网调峰影响的基础上,从电网、电源和高载能负荷三个方面提出了表征电力节能的指标并进行量化。最后基于综合模糊评价法对荷源联合调峰运行方案进行电力节能综合评估。仿真结果表明,该指标体系及方法在荷源联合调峰运行方案电力节能评估方面是有效可行的。
Bibliography:With regard to the contradiction between sharp transmission power loss and insufficient peak load regulation capacity caused by long-distance wind power transmission, it is proposed that high-energy load participate in conventional peak load regulation to realize energy-saving with wind energy consumption. Based on in-depth analyses of regulation features of high-energy load and influences that it may make on peaking, energy-saving indexes, considering power grid, power supply and high-energy load, are comprehensively proposed. In addition, comprehensive assessment of energy saving is made on peak load regulation scheme based on source-load coordination with the method of synthetical fuzzy evaluation. The simulation results show that the index system and method is effective and feasible in terms of evaluation of energy-saving on peak load regulation scheme based on source-load coordination.
