The aim of this project is to develop an integrated power plant through Virtual Power Plant (VPP) in order to respond to load demands by considering a corresponding power market product. The results show that the deployment of Multi-Agent based System (MAS) and Smart Grid Architecture Model (SGAM) concepts support the idea of the integration of intermittent RES (Photovoltaic) and flexible power generators (biogas, battery) in a VPP. The developed VPP quickly reacts to changing requirements (legal, economic, technical) without harming the stability of the system.
