Optimization and Assessment of a hybrid Solar-Wind-Biomass Renewable Energy System for Kiribati Island
Journal Title: International Journal of engineering Research and Applications - Year 2019, Vol 9, Issue 1
Abstract
This paper presents a feasibility study of photovoltaic (PV), wind, biomass and battery storage based hybrid renewable energy system (HRES) providing electricity to residential area in Australia. The monthly daily mean global solar irradiance and wind speed data of the capitals of the seven regions of the six states and various territories of Australia (Queensland, Northern Territory, South Australia, Tasmania, Victoria, Western Australia and New South Wales) are generated by the RETScreen Clean Energy Project Analysis Software produced by Natural Resources Canada. The long term continuous implementation of the system is simulated. The software HOMER produced by the National Renewable Energy Laboratory is used as a simulating tool. Their cost and emissions are compared with each other among the systems. It is found that an off-grid PV-wind-biomass HRE system is an effective way of emissions reduction and it does not increase the investment of the energy system. An off-grid hybrid energy system has been designed as well as simulated to support a small community considering an average load demand of 165.29 kWh/d with a peak load of 24.57 kW. The simulation and optimization of operations of the system have been done by HOMER software using the real time field data of solar radiation, wind speed and biomass of that particular area. The simulation ensures that the system is economically and environmentally feasible with respect to net present cost (NPC) and CO2 emission limitations. The result shows that NPC and CO2 emission can be reduced about 31.65%; equivalent to 16 tons per year as compared to conventional power plants. The NPC of the optimized system has been found to be about USD 294,382.00, having the per unit Cost of Energy (COE) of USD 0.381/kWh. The analyzed hybrid energy system might be applicable for other regions of the world where there are similar climatic conditions.
