Overview and analysis of the main technical-economic, regulatory and sociological prerequisites for the application of the peer-to-peer concept in electricity trading

U radu je opisan prijelaz elektro-energetskog sustava koji je započeo 1990. u članicama Europske Unije i nešto kasnije Hrvatske, iz centraliziranog oblika u tržišni sustav, te razvoj tog tržišnog sustava implementacijom koncepta naprednih mreža, poglavito mikromreža, virtualnih elektrana i uzajamne trgovine P2P koja može služiti kao osnova za razvoj napredne mreže. Opisane su tehnološko ekonomske, sociološke i regulatorne prepreke u ostvarenju P2P trgovine, kao i potencijalna rješenja problema koji se pojavljuju prilikom uvođenja novih subjekata na tržište električne energije, korisnika s vlastitom potrošnjom.This paper describes the transition of the electro-energy system that started in 1990 in the EU member states and later in Croatia, from a centralized form to the market system, and the development of this market system through the implementation of the concept of advanced networks, mainly microgrids, virtual power plants and P2P trade can serve as a basis for developing of an advanced network. Techno-economic, sociological and regulatory barriers to the realization of P2P trade are described, as well as potential solutions to the problems that arise when introducing new entities into the electricity market, users with their own consumption
