Real time implementation of intelligent reconfiguration algorithm for microgrid

Abstract

Microgrids with renewable distributed generation and energy storage offers sustainable energy solutions. To maintain the availability of energy to the connected loads and to interrupt the smallest portion of the microgrid under any abnormal conditions, reconfiguration is critical to restore service to a section or to meet some operational requirements. Reconfiguration is the process of modifying the microgrid's topological structure by changing the status (open/close) of circuit breakers or switches. This paper offers novel real time implementation of intelligent algorithm for microgrid reconfiguration. Intelligent algorithm is based on genetic algorithms (GA) and has been tested on two test systems including shipboard power system (SPS) and modified CERTS microgrid. Real time test bed utilizes real time digital simulator (RTDS) and commercial real time controllers from Schweitzer Engineering Lab. Reconfiguration algorithm has been implemented in real time using real time test bed for an example microgrid system and satisfactory results were obtained.

Recent Trends of the Most Used Metaheuristic Techniques for Distribution Network Reconfiguration

“…A similar methodology was presented in [35], where the selection process is carried out thanks to the roulette wheel, but there is a re-ranking process of the solutions acquired at each iteration, which gives the fittest ones a bigger change to have offspring. Other papers that deal with this topic are [46], [100], and [105].…”

Boundary Detection and Enhancement of Islanding Operation Investigation Under Fault Condition

“…However, in this paper, a boundary detection algorithm based on modified graph theory is proposed to identify the islands topology once they are formed. A simplified graph theory is utilized for different purposes such as microgrid reconfiguration [39] and load flow calculation [40].…”
