Optimal integration of photovoltaic generators into urban and rural power distribution systems Sol. Energy (IF 6.7) Pub Date : 2024-02-13 Jhony Andrés Guzmán-Henao, Brandon Cortés-Caicedo, Bonie Johana Restrepo-Cuestas, Rubén Iván Bolaños, Luis Fernando Grisales-Noreña
In this paper, we present a strategy for integrating photovoltaic systems into power distribution networks to improve the technical, economic, and environmental aspects of these networks. Taking into account variations in photovoltaic generation and energy demand, the proposed strategy uses a mathematical model that is subject to the technical and operational constraints of the system under analysis
