Design of 3 kW integrated power generation system from solar and biogas

Energy/Power is an important element of social and economic development. Without availability of energy at a reasonable price, there is little prospect of developing the country's economy and people's living conditions. A quarter of Pakistani population have no access to electricity, and currently a shortage of 5.0-7.0 GW power supply causes load shedding/blackout problems. In Pakistan, most of the power is generated from nonrenewable sources like natural gas etc. Pakistan receives almost 15.525 x 10(14) kW-hour of solar energy per year and sunshine duration is normally 8.0-10.0 h per day. Animal/farm wastes are readily available in Pakistan. Residues from these sources produce 103.0 billion m(3) of biogas per year that is equivalent to 63.20 TWh. The objective of this study is energy production by using easily available indigenous resources. In this study a 3.0 kW integrated solar/biogas power generation system consist of 2.84 kW solar system and 4.0 m(3) biogas system is designed and installed. This paper also present simulation model of system. A hybrid inverter is used to convert DC power of photovoltaic modules and the battery bank in to AC power and combines with the output power of biogas generator. Performance of the hybrid system are analysed from May 1, 2018 to June 15, 2018. During the test maximum power produce by the integrated system is 1.10 kW in morning, 2.14 kW in noon and 1.16 kW in afternoon. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
