Evaluation of wind-solar hybrid power generation system based on Monte Carlo method

Abstract

<span lang="EN-US">The application of wind-photovoltaic complementary power generation systems is becoming more and more widespread, but its intermittent and fluctuating characteristics may have a certain impact on the system's reliability. To better evaluate the reliability of stand-alone power generation systems with wind and photovoltaic generators, a reliability assessment model for stand-alone power generation systems with wind and photovoltaic generators was developed based on the analysis of the impact of wind and photovoltaic generator outages and derating on reliability. A sequential Monte Carlo method was used to evaluate the impact of the wind turbine, photovoltaic (PV) turbine, wind/photovoltaic complementary system, the randomness of wind turbine/photovoltaic outage status and penetration rate on the reliability of Independent photovoltaic power generation system (IPPS) under the reliability test system (RBTS). The results show that this reliability assessment method can provide some reference for planning the actual IPP system with wind and complementary solar systems.</span>

Hybrid renewable/grid power systems, an essential for base transceiver station penetration in Rural Nigeria

“…The choice of the two renewable energy sources (solar and wind) hinges on the fact that they are readily available energy sources across the country almost throughout the year at a sufficient quantity to generate the needed electricity. In Nigeria, the average monthly solar radiation stands at 5.8 kWh/m 2 per day, accompanied by an average of 6-7 hours of daily sunshine [7]. The coastal region experiences an annual average wind speed of around 2 m/s, while the far northern region experiences an average wind speed of 4 m/s [8].…”
