Legislative Assistance for Prosumer Energy within the Framework of Electrical Safety of Power Network

Published by Wiktoria GRYCAN, Wroclaw University of Science and Technology, ORCID: 0000-0001-8121-7612 Abstract. Prosumerism is inherently designed to be a tool that alleviates the grid. Still, not every prosumer aligns the consumption profile with the energy generation profile in photovoltaic installations. Therefore, the rapid development of Renewable Energy Sources (RES) in Poland, especially photovoltaic installations,Continue reading “Legislative Assistance for Prosumer Energy within the Framework of Electrical Safety of Power Network”
