Controlling voltage levels of distribution network-radial feeder after connecting wind turbines to the network

الملخص EN

Several factors in power generation and supply need to be taken into account such as shortages of energy supply, system stability, and energy quality and system disruption due to network losses, industrial development and population expansion.

The addition of wind turbines to the distribution network is of great benefit in providing additional power and solving these problems, but this addition is accompanied by the problem of low voltage network.

This research found optimal solutions to the problem of low voltage distribution network after connecting wind turbines.

The main idea of this paper is to optimize the low-voltage problem as a result of connecting the wind turbines to the "far end" of the radial feeder for a distribution network and to obtain a voltage level within an acceptable and stable range.

The problem of low voltage solved by using the load-drop compensation, capacitor-bank and “doubly-fed” induction generators.

The results of this study were based on the operation of the entire design of the simulation system which would be compatible with the reality of the energy flow of all network components by using the PSCAD program.

The present analysis program revealed an optimum solution for the low voltage profile of the distribution network after connecting the wind turbine.
