STABILITY AND CONTROL ASPECTS OF MICRO-GRID ARCHITECTURES OF WIND POWER SYSTEM

Voltage unstability nowadays is a serious problem, Present day electric power utilities are confronting numerous difficulties because of regularly expanding multifaceted nature in their task and structure. One issue that got wide consideration is voltage instability. One of the significant reasons for voltage instability in the power framework is with its receptive power limit. It can cause different damages to our electrical appliances, and therefore the approach used in this research is for the benefit for these dangerous phenomenon. In this research Voltage control single phase STATCOM using different sources such as Photovoltaic Cell, DC generator, battery and WAPDA used, in such a way to have a backup voltage source to have an untriptable supply, in case of less than 9 V the relay converter used the DC generator as back end source. It is a controller based system, controller on the basis of voltages changes the source to PV to DC and DC generator to Battery depends upon the voltages. Inverter is used which take input of 12 V that are controlled by relay in case of PV it is stabilized by buck converter. 1kVA Transformer then sets the voltage to 230V single phase, STATCOM is used after transformer to set the voltage at 230 V Power and Voltage monitoring system is used to check power and voltages at every point.
