A power management system for planned & unplanned grid electricity outages

Abstract

To deal with frequent planned and unplanned grid power outages, local energy systems are becoming popular idea. These systems are equipped with storage devices and different distributed generations (DGs) such as diesel generators. Efficient and reliable operation of local power systems is complex since power outages are stochastic events, and also local energy suppliers have different operation costs, constraints, and efficiency characteristics. A power management system (PMS), consisting of two control layers is developed in this paper to address aforementioned complex operation. To validate the proposed method, energy system of a base transceiver station (BTS) in India is simulated. It composed of batteries, diesel generator, real BTS load data, and a utility connection. In addition, the real historical outage data from India has been utilized to simulate outage events.
