In this book hybrid systems are studied and explained one by one with number of presented simulation results. Firstly we observe result of hybrid system and observe result of Stability analysis and proposed power management strategies using Homer Hybrid optimization Model of renewable energy resources. Hybrid Systems are found to be primarily exponentially increasing more penetration of renewable energy sources with availability and reduce burden on capital cost. The optimum and simulation values are observed on the basis of monthly data of wind and hydro. in case of MATLAB simulation hydro is more stable than wind, but in homer hydro cost is 22170$ and wind net present cost is 22000$. Instillation cost of wind is more than that of hydro power system later its proves to be very cheap.
