Abstract :
This paper presents a control strategy that aims to improve the parallel operation of two micro hydro power plants (MHPP) on an islanded micro-grid (MG). The two MHPP are equipped with a synchronous (SG) and an induction generator (IG). The proposed control systems ensures voltage and frequency regulation. The voltage is kept constant by the SG voltage controller, while the frequency by the use of a dump load circuit (SL). Besides this, the control system ensures active and reactive power management in order to reduce energy losses and optimize hydraulic resources utilization. Simulations are carried out in order to highlight the reliability of such a configuration.
