Grid tied solar inverters are designed to generate power at unity power factor which means that they have capability to produce active power only. The reactive power requirement of the load is catered by grid only. With the suddenly increase in the deployment of renewable based Distributed Energy Resources, reactive power drawn from the grid as compared to active power has increased considerably. The objective of this project is to present a local controller of reactive power to comply the new requirements asked by the transmission system operators despite the variation of ambient conditions...
