Standalone Hybrid Wind-Solar Power Generation System Applying Advanced Power Control Techniques

Abstract

In today’s world, due to the growing demands of technology and rise in population, there has been a tremendous pressure on the electricity demands. The world needs to find alternative sources of energy. Hence renewable sources are being considered to meet the growing demands of energy. This paper proposes a unique standalone hybrid power generation system, applying advanced power control techniques fed by four power sources are wind power, solar power, storage battery and diesel engine generator , and which is not connected to a commercial power system. Different power sources can be interconnected anywhere on the same power line, leading to flexible system expansion. A storage battery is installed within the solar power generation system, For instance, the battery is installed adjacent to the wind power generation system and a power device is used as control switch of dump load. Dump power is controlled as necessary to prevent battery overcharging. While these techniques construct a dispersed installation of different power sources, installation of dump load is necessary. Further, a high-tech dump load control method is necessary. Considerable effort was put into the development of active-reactive power and dump power controls. The result of laboratory experiments revealed that amplitudes and phases of ac output voltage were well regulated in the proposed hybrid system. It is anticipated that this hybrid power generation system, into which natural energy is incorporated, will contribute to global environmental protection on isolated islands and in rural locations without any dependence on commercial power systems.
