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 been presented to show the effectiveness of the proposed strategies.

The operating cost of islanded microgrids can be minimized by performing an optimal power sharing among the distributed generators (DGs) therein. In this study, a plug and play optimization scheme (PPOS) for developing nonlinear droop relations is proposed to achieve an optimal power sharing among the sources in islanded microgrids. The PPOS constructs nonlinear frequency droop relations that minimize the microgrid operating cost by adjusting the DGs output power. The construction of nonlinear droop relations is performed individually for each DG by optimizing each one against some user-defined reference DGs, which ensures an operating cost minimization irrespective of microgrid topology. An islanded microgrid model has been developed in MATLAB/Simulink environment to verify the effectiveness of the proposed method and the performance of the nonlinear droop control. An experimental study has been conducted on a microgrid test bench (MGTB) to prove the feasibility and performance of the proposed nonlinear droop control. I.978-1-4799-5776-7/14/$31.00 ©2014 IEEE

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 formulations. It can also be implemented in the local controllers and managed by the central controller. Numerical studies and experimental results illustrate the effectiveness of the proposed dispatching systems.
