Abstract

This paper presents a solar power source coupling model, as well as other distributed power resoures at households which are synchronized with distributive electrical grid. This synchronization uses frequency tracking control method, electrical grid voltage as well as solar power source. Investigation result of the method on the model recognizes that current stability capacity injects electrical grid to disregard voltage and frequency changes or direct source voltage of inverter system is reduced or increased. Besides, the model is capable of reducing creative power transmitting into electrical in order to take advantage of capacity of electronic interlocking of the inverter when transmitting active power.
