Abstract Recent developments in the electric utility industry is to encourage the entry of renewable energy sources for power generation in the distribution system. Wind energy systems, Photovoltaic systems, diesel engines and gas turbines are considered as Distributed Generators (DG). An Integrated Power Distribution System (IPDS) is a distribution system independent of grid that includes diesel generators, Wind Park, Solar Photovoltaic and batteries etc. This IPDS is considered for voltage stability analysis in the literature with Solar and Wind energy sources. However, it appears that no attempt has been made to reduce the losses using with integration of renewable energy sources. Further, optimal scheduling for integration of Distributed Generators (DG) is not considered in the literature so far. The main objective of this paper is to reduce the diesel consumption and losses by utilizing the energy from renewable energy sources and battery storage. The optimal scheduling of the distributed generators in IPDS is also considered. IEEE 14 Bus system is analyzed with Wind, Solar, Battery, Diesel generation and Static Var Compensator (SVC) using Power System Analysis Toolbox in MATLAB.

utilization. Wind energy and Solar energy are the two renewable energy sources most common in use. Wind energy has become the least expensive of renewable energy technologies in existence. Photovoltaic Cells (PVC) convert the energy from sunlight into DC power [1]. PVC offer added advantages over other renewable energy sources and require practically no maintenance. Hybridization of wind and solar power sources provide a realistic form of power generation. Renewable energy generation offers clean, abundant energy gathered from self-renewing resources such as wind and the sun etc. When the power demand increases, generation also should increase. So, renewable energy sources can be used to supply constant loads. The distributed generations have several advantages such as reducing the real power loss, required transmission capacity and the traditional generation expansion, etc. [2]. The output of wind and solar generators is determined by the climate and weather conditions [3]. The effect of wind power on the transient fault behaviour is considered by replacing the power generated with two wind tur
