A strategy for voltage and reactive power control of an autonomous industrial power system including distributed generators and loads is presented. The investigation is based on time-domain simulations and aims to define the main functions for the power management system (PMS) that will govern the operation of the power system. Inter-bus transformers (IBTs) are used to limit the fault level but will affect the sharing of the total load reactive power between distributed generators. Generator AVR and on-load tap changing of the IBTs, both supervised by the PMS, are used together to regulate the local load voltages and at the same time to allow reactive power flow through the IBTs for the purpose of equalised sharing. A coordinated strategy is obtained. The knowledge gained from this study can be useful in future cases.
