Abstract
The participation of demand response in power system regulation is an effective supplement to generation side regulation. In order to fully tap the potential of demand side resource regulation, a bi-level optimization model of distribution system is designed considering the interaction and transaction mode among the power grid, distribution system operator (DSO) and load aggregator (LA), and the role and transaction object in the response of each subject are clarified. The upper level considers the coordination and interaction of the internal source, load, storage and LA of DSO, and optimizes the dispatching of the distribution system with the goal of maximizing the profit of DSO; The lower level aims at maximizing LA’s profit of aggregating inverter air conditioners and electric vehicles. Based on the actual operating characteristics of inverter air conditioners and electric vehicles, the demand response model is constructed to fully tap its regulation potential and formulate load regulation strategies. In terms of model solving, the bi-level optimization problem is transformed into an easy to solve linear programming problem through KKT condition and big M method. The example results show that this bi-level model can fully tap the regulation potential of LA, reduce the purchase of electricity from the main network, and improve the income of DSO and LA.
