Influence of Optimizing Prosumers on Urban Distribution Networks

Abstract:
Due to the increasing use of decentralized energy generation and storage facilities, the integration of electric vehicles, the coupling of thermal and electrical energy systems (hybrid systems or sector couplings, heat pumps, air conditioning systems) and also through the increased use of information technology (ICT) in the networks and even at the consumer/prosumer level, low- and medium-voltage grid operators in particular are facing new challenges. The aim of the of the presented work is to investigate the influence of optimizing consumers and prosumers on the various objective functions of optimization (e.g. economic, ecologic ...) on the exchanged power at a LV-transformer of an exemplary low-voltage network. It will be shown to what extent you can still control the load flow at selected optimized consumers/prosumers by e.g. intelligently selected tariffs. Possible effects of dynamic tariffs taking into account the interaction between self-optimizing consumers and low- and medium-voltage grid operators are presented in this paper.
