Low voltage power distribution networks have undergone considerable changes in recent years. Their conventional structures of operation and control are being challenged, mainly by the large-scale integration of distributed generators based on Renewable Energy Sources and the increase in demand. In this scenario, not only new challenges appear, but also opportunities. The widespread deployment of “smart meters,” together with the desire to include citizens as fundamental players in future energy markets and system operations, through power generation or the provision of demand flexibility, is playing a key role in the new era of power systems. This work proposes a logic heuristic model working with a tool for electric power system simulation and analysis – MATPOWER – to enhance the Demand Response participation of small consumers and dispatchable distributed renewable energy sources flexibility to mitigate the voltage and congestion problems in low voltage distribution power networks. To demonstrate the applicability of the proposed model a realistic 400V low voltage distribution network with 236 buses, 96 loads, 55 Electrical Vehicles charge stations, and 3 dispatchable generators. The results show significant improvements in the voltage and congestion profile.
