The effect of demand response on operation of smart home energy system with renewable energy resources

In this paper, a model is proposed for operation of a microgrid considering non-operational production, i.e. wind turbines and solar system, and energy storage system as well as customers. This microgrid is capable of bilateral exchange of energy with upstream network. In addition, in this mircorgrid, there exist two general types of controllable and non-controllable loads. For the former types, by proposing operational models and new control, their amount of consumption is varied based on wind turbine and solar radiation intermittence, upstream system price, and customers' welfare level or the consumption amount is transferred to another time. This control performance leads to rewards and/or penalties in consumed power prices. For this optimization program, an objective function from the microgrid manager's viewpoint is extracted and is maximized using particle swarm optimization. Finally, optimal operational schedule is suggested for a sample microgrid and the results of simulation are analyzed and compared to consider load control programs in its operation.
