    Abstract: Systems and methods are disclosed for multi-objective energy management of micro-grids. A two-layer control method is used. In the first layer which is the advisory layer, a Model Predictive Control (MPC) method is used as a long term scheduler. The result of this layer will be used as optimality constraints in the second layer. In the second layer, a real-time controller guarantees a second-by-second balance between supply and demand subject to the constraints provided by the advisory layer.

    Abstract: A computer-implemented method for controlling a distributed energy storage system (ESS) communicating with one or more microgrids is presented. The method includes assigning, via the processor, a weight to a first objective function pertaining to minimizing demand charge (DC) cost, assigning, via the processor, a weight to a second function pertaining to maximizing photovoltaic (PV) utilization, receiving historical demand profiles including demand data and historical PV profiles including PV data, and determining ESS power and capacity. The method further includes employing a multi-objective DC cost and PV utilization optimization module to obtain a plurality of optimal solutions by concurrently processing the assigned weights of the first and second objective functions, the historical demand and PV profiles, and the ESS power and capacity.
