Wind power integration improvement in the electric network

The wind turbines integration into the electric network remains limited because of their uncertain and difficult prediction of production. This paper presents some solutions to improve the wind power integration rate in the network while maintaining its stability. The study is based on the use of regulators and FACTS (Flexible Alternating Current Transmission Systems) systems. We presented in a first step the various power grid components models as well as regulators and FACTS system. Then, the maximum wind turbines integration rate has been calculated for different cases after checking the power grid stability criteria. All simulations were achieved on a modified test network IEEE 14 nodes using the Matlab-based toolbox (PSAT).
