Cooperative Operation and Revenue Allocation Mechanism in Networked Multi-Energy Microgrids

Abstract

Multi-energy microgrids can promote the complementary resources of each entity and improve economic efficiency through cooperated operation. However, the efficient collaborative operation faces the problem of maintaining the stability of the coalition, i.e., to make sure that all individuals will not experience economic loss. To address this problem, this paper first introduces a model for the operation of networked multi-energy microgrids. Then a cooperative revenue allocation mechanism based on the asymmetric Nash bargaining method, with net power output as the contribution measure to guarantee the stability of cooperative alliances is proposed. Finally, a numerical test on a 3 multi-energy microgrid systems is conducted to validate the proposed method. The results show that the proposed cooperative revenue allocation mechanism can not only effectively reflect the differences in the contribution degree of each entity within the coalition, but also avoid the problem of overly aggressive allocation compared with the Shapley value-based allocation mechanism.
