<p>Wind is available with free of cost anywhere in the world, this wind can be used for power generation due to many advantages. This attracts the researchers to work on wind power plants. The presence of wind power plants on distribution system causes major influence on voltage controlled devices (VCDs) in terms of life of the devices. Therefore, this paper proposes grey wolf optimization method (GWO) together with forecasted load one day in advance. VCDs are on load tap changer (ULTC) and capacitors (CS), there are two main objectives first one is curtail of distribution network (DN) loss and second one is curtailing of ULTC and CS switching’s. Objectives are achieved by controlling the reactive power of DFIG in coordination with VCDs. The proposed method is planned and applied in Matlab/Simulink on 10KV practical system with DFIG located at different locations. To validate the efficacy of GWO, results are compared with conventional and dynamic programming methods without profane grid circumstances.</p>

Abstract Installation of a wind power distributed generator in a distribution system alters the reactive power drawn by the system. This affects the load bus voltages. Any deviation in load bus voltages from their limits is sensed by an on load tap changer of a transformer and it responds to maintain the bus voltages within their limits. The reactive power requirements of a wind generator vary due to the intermittent behaviour of wind, which will in turn vary the bus voltages. This has an affect on number of tap changings of a transformer. Frequent tap changing of a transformer increases wear and tear of it and ultimately reduces the life of it. A mathematical model is developed to analyze the voltage sensitivity at a load bus to the tap change of a transformer under different scenarios and conditions in the distribution system. A possible solution to reduce the number of tap changings is presented in this paper.

AbstractThe ever-growing demand for energy sources of low environmental impact has given a greater importance to wind farms in many countries. However, due to operational characteristics of these complexes, which are reflected into a variability of the energy produced and in the use of power electronic converters, the interaction between wind power plants and electrical networks shows itself to be an area of high investigative interest. In fact, among the various phenomena that exist, steady state voltage variations constitute a theme that is under the constant attention of electrical system operators. In this context, the present article is directed toward the analysis of a voltage regulation strategy aimed at wind power generation systems composed by synchronous machines and full converters. Once established the methodology that lead to an ancillary operation of the wind farm, the authors present results of computational simulations on ATP/EMTP platform that attest to the efficiency of the strategy.
