Summary
Exponentially growing global populations and equally increasing power requirements have become matter of concern to people from all walks of life. This puts pressure on utilities to increase the generation capacities. This simply means more burning of fossil fuels (coal, crude oil, and gas) and addition of harmful gasses in to the local and global atmosphere. These emission of harmful gases, pollute the environment and cause unnatural weather modifications which results in catastrophes on our planet. Hence, to control such adverse changes of the climate and minimize the environmental disasters, new, clean, renewable, and distributed sources of energy must be encouraged to safeguard our forthcoming generations. Such sources include wind, solar photovoltaic (PV), solar thermal, geothermal, hydro, tidal, biomass, biofuels, etc. Among these renewable energy sources, wind and solar are being widely used due to its ease of availability, installation, maintenance and operation. Renewable sources are distributive in nature and can be harnessed anywhere and anytime for all sizes of application irrespective of geographical location. These sources are being used for grid connected large applications and are also for small applications at locations which are not connected to the grid.
People living in remote areas of developing and some of the developed countries have low access to the grid generated electricity. They depend on diesel generated electricity which is costly and also labor intensive. Hybrid Power System (HPS) deliver an excellent solution to this problem as it entails the advantages of both conventional and renewable energy sources. The global hybrid power system market is expect to grow at a compound annual growth rate of 8.34% from 477.71 million $ in 2017 to 836.92 million $ in 2024. Hybrid power system concept is based on using more than one source of energy to supply electricity to small dwellings and other remotely located applications such as communication towers, meteorological stations, and so on. The major components of the hybrid power system include the combination of common bus, wind turbines, photovoltaic panels, power converters, batteries, fuel cell, biomass gasifiers, etc. depending on a particular configuration of the power system. These system take the advantage of multiple sources of energy and assure continuous power. The hybrid power systems may be of the following types:
• Wind-Diesel hybrid power systems with or without battery backup (WND-DSL)
• Solar photovoltaic-Diesel hybrid power system with or without battery backup (PV-DSL)
• Wind-solar photovoltaic-Diesel hybrid power system with or without battery backup (WND-PV-DSL)
• Wind-Diesel-Fuel Cell hybrid power system (WND-DSL-FC)
• Solar photovoltaic-Diesel-Fuel Cell hybrid power system (PV-DSL-FC)
• Wind-solar photovoltaic-Diesel hybrid power system (WND-PV-DSL-FC)
Wind-solar photovoltaic-Biomass hybrid power system with or without battery backup (WND-PV-DSL-BIO), etc.
