Abstract:

This paper presents an innovative voltage regulation strategy developed using proportional-integral-derivative (PID) control and the reactive power injection capability of PV inverters. The implementation of a consensus-based control algorithm considers the different possible operation conditions and hence provides better performance of low-voltage distribution networks with dynamic switching loads. Simulation studies indicated enhanced stability of networks, resulting in significant voltage fluctuation reduction. This makes it one of the effective and widely applicable solutions to customers for voltage regulation at LVDNs by taking maximum advantage of the reactive power control features of PV inverters. Because it has been designed for systems with high sharing of distributed renewable energy, improved voltage profiles and increased stability in the network will result in substantial progress in the electrification of modern distribution systems
