A Statcom-Control Scheme for Grid Connected Hybrid Wind-Solar Energy System to Improve Power Quality
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 1
Abstract
Hybrid wind-solar renewable energy sources are alternative energy sources. It is connected to the power grid. The electric power Generated from wind and solar energy system is always fluctuating due to the nature of fluctuation in the wind and solar. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed According to the guidelines specified in International Electrotechnical Commission standard, IEC-61400. The power quality measurements are: active power, reactive power, filicker, harmonics, variation of voltage, and electrical behaviour of switching operation. This paper clearly shows the existence of power quality problem due to installation of wind turbines with the grid. In this proposed scheme of a STATCOM is connected at a point of common coupling with a battery energy storage system to reduce the power quality problems. It energy storage system is integrated to support the real power source under fluctuating wind and solar power. A STATCOM control scheme to compensate the reactive power demand of the load and the induction generator. To improve power quality at the main supply source. In this paper THD is reduced to 1.23% from 13.28%.
