Unit Sizing and Cost Analysis of Renewable Energy based Hybrid Power Generation System - A Case Study

A simulation model is developed for optimal sizing and analysis of a PV-diesel-battery based hybrid power generation system with the objectives to minimize life cycle cost and CO 2 emission, while maintaining the desired system autonomy. A case study of a boy’s hostel in Moradabad district is taken for analysis purposes. It has 91 rooms with a capacity of 3 boys in each room. The decision variables included in the optimization methodology are total PV area, number of PV modules of 600 Wp, diesel generator power, fuel consumption per year and number of 24 V and 150 Ah batteries. The simulation result shows that the PV percentage of 86 % and diesel penetration of 14 % gives the most optimized solution with minimum LCC of $110,547 and average CO 2 emission of 28 kg/day. The developed model has been validated by comparing its results with earlier research work. doi: 10.14456/WJST.2014.24
