Energy exchanging control in multiple microgrids with transactive energy management

Abstract

In recent years, the advent of microgrids with numerous renewable energy resources has created some fundamental challenges in control, coordination, and management of energy trading between microgrids and the power grid. To respond these challenges, some techniques are proposed to control of the energy sharing, which one of the reliable of them is transactive energy (TE) technology. Therefore, this paper uses TE for energy exchanging control among the microgrids with applying the two operational cases for analysis the control of the energy trading of four microgrids along with minimizing the energy cost of each microgrid. In this regard, Mont Carlo simulation and fast forward reduction methods are used for scenario generation and reduction for the uncertainty parameters, respectively. First case is assumed that all microgrids can only receive energy from the network and have not any connection with each other. In order to maximize energy cost saving of each microgrid, second case is proposed to provide a positive percentage of cost saving for microgrids. The simulation results of this paper indicated that microgrids not only can achieve the positive cost saving in second case, but also their total energy cost has been reduced in comparison of first case.
