摘要
电网投资建设规模持续增长,迫切需要一种电网规划精准投资方法,提高电网投资的经济效益。提出一种基于全生命周期投入产出效益的电网规划精准投资方法。首先,针对电网规划投资需要解决的不同问题,制定典型的电网规划投资场景,并分为刚性需求场景和弹性需求场景两类,统筹考虑不同场景所侧重的投入产出效益,建立电网规划全生命周期投入产出效益的综合评价指标体系和评价方法;其次,选取6种典型电网规划投资场景,为每种场景制定2种可行的规划方案,对不同规划方案进行全生命周期投入产出效益计算,并按照效益水平对可行方案进行优化比选,得到各种场景下的最优方案,按照优先考虑项目重要性、其次考虑项目投入产出效益的原则对最优方案排序,按照最优方案排序表,逐一安排项目,直到项目投资金额大于总投资计划或者安排完所有项目,得到电网规划投资的项目安排结果,实现电网规划精准投资;最后,结合某省级电网进行实证分析,结果证明该方法具有可行性和实用价值。
Power grid construction investment continues to grow and needs accurate investment method in power grid planning to improve economic efficiency.In this paper,a new method of the accurate investment of power grid planning(AIMPGP)based on full life cycle input-output benefits is proposed.First,considering the variety of power grid planning investment application scenarios,different scenarios are compared and selected based on input-output benefits,putting forward a comprehensive benefit evaluation index system and an evaluation method of power grid planning in different application scenarios.Secondly,six kinds of typical power grid planning investment scenario are chosen,and two feasible projects are refined for each scenario.Then,the optimal scheme set is divided into rigid demand and elasticity demand.Specifically,when the plan of investment funds is lower than the total investment demand,the rigid demand-type grid investment plan should be satisfied,and the flexible demand-type projects are arranged from high to low according to the investment efficiency level,until the investment plan of the grid project meets all the requirements.Finally,a provincial power grid is analyzed based on the proposed methods to demonstrate its feasibility and practical value.
