On the optimal demand-side management in microgrids through polygonal composition Topa, A.O. Calvo Cruz, Nicolás Álvarez, J.D Torres, J.L. Demand-side management Microgrid Optimization This article presents a novel methodology for energy management in microgrids focused on the demand side. It is inspired by the Tangram puzzle. The energy demand and production profiles are represented by polygons and managed through computational geometry. Therefore, an optimization problem is defined to place n energy demand profiles (pieces) to cover the total energy production profile (target shape). The optimization problem is addressed with a genetic algorithm. It tries to calculate the optimal positions of the polygons of the demands covering the maximum energy production. Since the referred production comes from renewable energy sources in the microgrid, this method allows reducing both the consumption of fossil fuels and energy bills. 2023-09-28T10:33:43Z 2023-09-28T10:33:43Z 2023-05-11 journal article A.O.
