Abstract PV-battery hybrid systems of DG can play an important role in decentralized electricity generation based on especially in remote locations. the first part of the thesis deals with modelling the PV-battery hybrid system for DG decentralized energy production based on actual plug-in hybrid system, located at the Institute of resources Executive residential complex preparation (TERI) energy and located in Gurgaon near Delhi. detailed model based component was prepared in MATLAB/Simulink and checked against the specifications of the manufacturer. The various modules, which have been prepared for this model () module, solar radiation, photoelectric module (b), © maximum Power Point Tracker module (d) module array (e) the executable file (F) shipping module (g) battery module (h) battery module (I) DG, and approval (J) economic power dispatch module module was modeled on operating bandwidth limitations and specifications of the converter set DG and current battery charging and operating voltage limits, as provided by the manufacturers. Operating strategy in this module can be changed as needed. the economic module was developed to calculate the cost of delivered energy hybrid systembased on an analysis of the life cycle. the second part of the thesis is a parametric tests to define the criteria for determining the size of the hybrid system with the use of different operating strategies.The model was modeled using the existing distribution strategy with annual actual load curve and curve-based load average daily demand. It was found that the performance of the hybrid system is very sensitive to the load curve model also simulated using alternative operating strategies. It was found that the total amount of monthly losses averaging system in the existing supervisory policies were about 20 per cent, while in the alternate strategy of dispatching hybrid system losses were 4 percent. the model is also used to simulate the PV system without installing DG. It was found that the hybrid system is not only cost effective, but also had a significantly lower loss, the PV-SAS. Modeling showed that average daily energy requirement the basis for designing the hybrid system will lead to sub-optimal design system. future work in this area will be to develop a search algorithm for arriving at an optimal design system for the optimal system design LOLP also very closely associated with operating strategies, which should be part of the search algorithm.
