OPTIMAL OPERATION OF BIOMASS/WIND/PV HYBRID ENERGY SYSTEM FOR RURAL AREAS

In this article, a hybrid energy system consisting of biomass, wind, solar photovoltaic (SPV), and battery is proposed. The sources are operated to deliver energy at optimum efficiency. An optimization model is developed to supply the available energy to the loads according to the priority. It is also proposed to maintain a fair level of energy storage to meet the peak load demand together with biomass, wind, and solar photovoltaic during low or no solar radiation periods or during low wind periodsA case study was completed using load data collected from three villages (300 km south of Chennai, India). Simulations carried out for a one-year period proved the effectiveness of the developed energy management system by satisfying the load demand, nonlinear seasonal variations, and equipment constraints. Also with the proposed energy management, it is found that the load demand is almost satisfied, there is less dumped energy, and the state of charge of the battery is at a reasonably good level. Economic analysis is also carried out and the cost of energy is found to be Rs. 4.20 (US$ 0.1095).
