Contribution-based Energy Scheduling of Cooperative Microgrids

This paper proposes a new energy management framework for the coordinated control and management of multiple-coupled microgrids. The objective is to encourage inter-microgrid power exchanges, thereby reducing the demand and reliance on conventional grid power. In order to achieve this objective, a contribution based power scheduling scheme is embodied, that regulates the power exchanges between microgrids within a coalition and that with the upstream grid. Microgrids are prioritized based on their current power demands and their previous contributions to the coalition. Through the proposed framework, microgrids are thereby, rewarded with priority in the present time interval, for their contributions to the coalition in the past. Various system intermittencies are modelled using the scenario generation and reduction processes. Eventually, the efficacy of the proposed framework is verified using several case studies and comparative analysis.
