摘要
降低建筑能耗是实现“双碳”目标的重要路径,其中建筑配电系统规划扮演着重要角色。依据源-网-荷-储各部分特征,建立了建筑使用过程中的能耗和配电总成本模型。形成了限定能耗下的成本最优的“光伏+储能”规划问题,并用Benders分解法求解。考虑实际设计参数存在多种备选方案,利用原规划问题的灵敏度模型实现了参数优选,并制定了规划和参数调整两步迭代流程。最后,单层展厅案例研究表明该规划方法切实有效,可在限制运行能耗时降低成本,利于低能耗建筑的推广。
It is a key avenue of carbon peaking and carbon neutrality goals to reduce energy consumption of buildings,and distribution system planning of buildings plays an essential role in it. According to the characteristic of each part of source-network-load-storage,a total cost model of energy consumption and distribution for buildings is established. An energy-limited“photovoltaics plus storage”planning problem with optimum cost is proposed and solved by Benders decomposition. Given alternatives of design parameters,the optimum selection of parameters is realized by the sensitivity model of the initial planning. Besides,two iterative procedures of planning and parameter adjustment are formulated. Finally,a case study of a single-story exhibition hall reveals that the planning method is practicable and effective;it can curtail energy consumption of operation and costs and help promote buildings with low energy consumption.
