This paper presents results of the development of a voltage and power management system for a microgrid. The microgrid under study is a power system located on the island with a peak load of 1.8 MW connected to the main power grid via two submarine cables. Due to a long radial network configuration with a high ratio of resistance to reactance, the system experiences low voltages problems at remote locations. In addition, during peak load conditions, thermal ratings of the submarine cables can be violated. Integration of the local diesel generator and energy storage system is proposed to overcome existing problems. The proposed voltage and power management scheme coordinates the on-load tap-changing (OLTC) transformer, diesel generator and energy storage system of the microgrid. The scheme ensures that the voltage profile of the microgrid is maintained within Electricity Code under peak conditions. Results of the study are presented and discussed.
