This paper considers the power sharing stability of a grid connected Micro-grid (MG) system with three Distributed Generation (DG) units via Power System Stabilizer (PSS). Various PSS structures are employed and compared in order to achieve the best transient response under different DG penetration levels. Particle Swarm Optimization (PSO) is used to tune to controller parameters. The optimal controller's...
Micro-grids (MGs) are active networks known as an effective solution for the control of grids including high levels of Distributed Generation (DG). In off-grid MGs, DGs connected to Voltage Source Inverters (VSIs) enroll as controllers of voltage and frequency. These VSIs should share power between the DGs fairly. A precise power sharing may increase frequency drop. In this paper, a trade-off is obtained...
