Optimal Dispatching Strategy of Load Aggregators Considering Peak Load Shifting

Load aggregators can help residents aggregate their loads to better participate in demand-side response in electricity market. For residents, the characteristics of flexible loads can be classified as adjustable and non-adjustable characteristics, transferable and non-transferable characteristics, interruptible and non-interruptible characteristics. Based on these characteristics, an optimal dispatching strategy of aggregated loads is proposed in this paper. For load aggregators, with the object of peak load shifting, an optimal dispatching strategy is developed. Then, to estimate the revenue of load aggregators, a settlement model is established. Case study results verified the validity of the proposed dispatching strategy, which can not only help distribution network reduce the peak and valley difference, but bring these load aggregators and residents extra benefits from the distribution network.
