However, due to the variable nature of renewable generations, load changes and grid contingencies, the system suffers from significant fluctuations of power, voltage and frequency. This paper seeks to present comprehensive converter control solutions for power sharing coordination and stabilization of voltages and frequency to ensure high power quality and reliability in a networked microgrid system regardless of its grid-connected and islanded modes of operation. The control solutions are provided in d-q axes for both active and reactive powers. The multilevel inverter topology that is designed to interface the distributed energy resources results in better suppression of output harmonics compared to that with a conventional 2-level inverter. The paper also features an interlinking algorithm framework of particle swarm optimization (PSO) to tune the control parameters for the optimized performance of converters. A prototype of grid-connected system of three microgrids is simulated in PSCAD platform to validate the efficacy of the proposed solution.

Maximization of network load-ability without compromising the system stability has become a major concern for them. Introduction of FACTS technology can help a system to achieve these goals without building new transmission lines that is both expensive and time consuming. However, the new installation of FACTS in the system has to be optimal in terms of its type, location and size. This paper seeks to present a genetic algorithm based framework that can optimize a system having FACTS devices with an objective of improved economic dispatch. The IEEE 14 & 30 bus systems are taken as illustrative examples to validate the effectiveness of proposed method.
