A Local Electricity Model for DER Aggregator at a Distribution Network Level

This Paper proposes a fully Decentralized Day ahead (DA) local electricity market (LEM) model which facilitates smooth market design in a restructured power System. LEM has local producers and consumers like PV, WT, DG and energy storage systems. The main objective of this model is to mark the challenge of integrating DERs into a grid that enables to trade energy with the operator at distribution level. As LEM involves DERs whose capacity is insufficient to incorporate a market model DER aggregator (AG) is one of the possible solutions. The proposed model involves a DA market where AGs submit their bids to DSO and the DSO clears the market at the lowest possible price by considering all technical constraints of the network. The Proposed model is evaluated through a case study of a modified 33-bus test system which shows effective energy trading at a distribution system with a considerable marginal range of violations.
