Utilizing MINLP-based Hourly Dispatch Optimization on a Droop-Controlled Islanded Microgrid

Abstract

True to any profit-generating endeavors, the concept of reducing costs in order to maximize profit has always been there. In the context of islanded microgrids utilizing renewable energy, this comes in the form of reducing fossil fuel consumption, with the added bonus of also reduced CO 2 emissions. In the case of microgrids with multiple parallel operated diesel generators, there exists an optimal dispatch for the least amount of diesel consumed at any given loading condition. This paper presents a dispatch optimization algorithm for droop-controlled islanded microgrids in the form of a MINLP.

An Adjustable Differential Protection Scheme for Microgrids with Inverter-Based Distributed Generation

“…Different microgrid protection schemes have been suggested recently in the literature against faulty situations. The authors of [8]- [10] proposed an adaptive scheme for a microgrid with synchronous generators. The authors of [11] proposed a protection centre to adaptively monitor the currents of the feeder continuously.…”
