Energy Management of a Grid-Connected Microgrid Based on Linear Programming: A Case Study of Beni Mellal Province

Abstract

This article examines the potential benefits for a user or an industrial company in Morocco operating a self-production microgrid, when the injection and sale of surplus local production become possible, notably thanks to the presence of an EMS. The objective is to highlight the importance and impact of surplus injection compensation on the overall costs and benefits for self-producers, especially in the industrial sector, and to support the acceleration of legal procedures related to electricity injection into the national grid, as well as the official publication of feed-in tariffs. To optimize producers' gains, an energy management strategy based on a linear programming optimization method is developed and analyzed. This strategy is evaluated under two scenarios: free injection of surplus energy and injection with sale at a reference tariff inspired by neighboring countries. Simulations are used to assess the impact of this approach on the company's energy costs and highlight the economic viability of establishing a legal framework for compensated electricity injection into the national grid.
