摘要

分布式发电(distributed generation,DG)的接入改变了传统配网的供电模式,对配网电压质量、继电保护、短路容量、潮流流向都会产生较大影响。为研究DG的接入对配网影响及在各运行条件约束下配网所能接纳最大DG容量,以典型10 kV配网为例,分析其对配网电压质量影响的前提下,以DG极限接入容量为优化目标,综合考虑电压偏差、电压波动、短路电流、线路载流量、潮流方程约束及分布式出力约束,采用粒子群优化算法求解得到配网在多节点同时接入DG情况下的最大接入容量,仿真及优化结果表明了所提模型与算法的有效性。

Abstract

The distributed generation (DG) access has changed the traditional power supply mode of the distribution network, and has a great impact on the voltage quality, relay protection, short-circuit capacity and power flow direction of the distribution network. In order to study the influence of DG access on distribution network and the maximum acceptable capacity of DG under the constraint of distribution network in various operating conditions, taking a typical 10 kV network as an example, this paper analyzes the effects of DG access on the voltage quality of distribution network;then, taking distributed limit access capacity as optimization objective, with considering the voltage deviation, voltage fluctuation, short-circuit current line, carrying capacity of line, power flow equations constraints and distributed output constraints, adopts particle swarm optimization algorithm to solve this optimization problem to obtain the maximum access capacity when the distribution network is connected to DG in multi node at the same time. The simulation and optimization results show that the proposed model and algorithm are effective.
