This paper introduces a distributed economic dispatch strategy for microgrids with multiple energy storage systems. This strategy overcomes the challenges of dynamic couplings among all decision variables and stochastic variables in a centralized dispatching formulation. The proposed strategy can be implemented in the microgrid central controller as multiple problems with simplified and decomposed...
This paper presents an optimal scheduling strategy that decouples the dynamic formulation for dispatching energy storage units from dispatching ac grid power exchange in microgrids. This method takes into account the time-of-use price of electricity. It also considers initial stored energy as a decision variable in the optimization process instead of a fixed parameter. Case studies and results have...
In this paper, an energy management system for Multi-port Power Electronics Interface (MPEI) is developed to be used in public electric vehicle charging stations. The MPEI has power electronic converters to interface with the utility grid, photovoltaic panels, battery energy storage, and the loads. In order to achieve a minimum daily utility cost, the proposed energy management system provides an...
