Analysis method of weak point for high voltage distribution network with high density distributed generation

High voltage distribution network is an important link between transmission and middle voltage distribution network. If a high voltage distribution network fault occurs, the economy and reliability of the whole city distribution system will be seriously affected. To solve this problem, a traditional reconstruction optimization model is improved and a 2-staged reconstruction optimization model is proposed based on an improved particle swarm optimization (PSO) algorithm. The first stage reconstruction only considers the economic goal and the second stage reconstruction needs consider the boundary constrains. The 2-staged method considers the economic benefit and the voltage quality simultaneously. It can achieve the multi goals: meeting actual boundary operation conditions, optimizing the combination of network losses and the number of operation switching. The fault isolation and reconfiguration of an actual distribution network system in Dezhou power grid were simulated. Simulation results validate the rationality and feasibility of the proposed method

The Impact

From the angle of voltage distribution, the influence of DG on power network was studied, various access position and access capacity of DG were analyzed, and conclusion can be drew that DG can help optimize the voltage distribution in the power network. Besides, the output of photovoltaic and wind power was characterized by varying with time, and based on that, the voltage distribution was simulated when they were both connected in the same distribution network. According to the simulation result, some valuable principles and necessary procedures have been proposed.
