Abstract
With the development of distributed energy resources (DERs) and the increasing flexibility in active distribution networks (ADNs), the economic operation of ADN components on both generation and demand sides to improve power self-consumption capability are required to be studied. In this paper, by considering the electricity price response of energy storage (ES) and flexible load (FL), an interactive and coordinated operation strategy for ADNs is presented based on a bi-level multi-agent system (MAS) structure. In the situation of power imbalance, each active component agent will be informed by higher level ADN agent and make their own response based on the technical operability and economical consideration. ADN agent will finally coordinate each participant and develop operation strategy by using the interactive benefit prioritization principle. The simulation results indicate that the proposed interactive coordination strategy can not only maximize the consumption of renewable energy, but also reduce the power imbalance and improve the economic operation of ADN.
