Therefore, renewable energy is a hot topic these days. They are renewable, sustainable and environment friendly. The increase in renewable generation, on the other hand, can affect many power systems issues in different ways. One of these issues affected by renewables is power systems security. Since power systems are always subject to different contingencies, contingency ranking in power system is very important. This paper tries to evaluate the effects of wind power on power systems security in various conditions of wind generation penetration into the conventional power system. In addition to using fuzzy logic to get a flexible performance index (PI), the proposed method is dealing with Monte Carlo Simulation (MCS) to simulate the stochastic behaviour of wind Generation. Finally, the proposed method is simulated on IEEE-RTS with satisfactory results and the results are discussed. %U https://sciarena.com/article/security-evaluation-of-power-systems-in-various-conditions-of-wind-energy-penetration-using-mcs
