摘要

随着分布式发电渗透率的不断提高，电力系统综合运行效率不高、“源网荷储”各环节协调不够、各类电源互补济不足等问题逐步显现。对“源网荷储”进行分层分区平衡有助于解决这些问题。在此背景下，采用配电系统网格化规划方法，按照并网型微电网运行规则，提出面向网格的多元化用电需求分析方法和“源网荷储”分层分区平衡模型，以及配电系统网架优化设计内容。所提方法已被应用于实际系统规划，实践结果表明所提方法可有效降低用户的最大负荷需求、改善系统整体负荷轮廓、提高线路负载率、降低电网投资规模，有助于实现源网荷储各环节协调发展，从而提升电力系统运行的安全性和经济性。

Abstract

With the constantly increasing penetration of distributed generation

some problems such as the low comprehensive operation efficiency of the power system concerned

insufficient coordination among the so-called“source-network-load-storage”

and inadequate complementarity among various types of generators are becoming more and more significant. Implementing hierarchical partition balance of“source - network -load - storage”could address these problems.Under this background

according to the operation rules of a grid- connected microgrid

a diversified power demand block analysis method and a“source-network-load-storage”hierarchical partition balance model are presented

and related optimal design of the distribution network concerned addressed. The proposed method has been employed for actual distribution system planning

and the implementation results demonstrate that this method can effectively reduce the maximum load demand

improve the load profile of the whole system and the load rates of lines

reduce the scale of required network investment

realize coordinated development of“source - network - load- storage”

and finally improve the security and economics of the distribution system.
