Baoxiang An, Zhenping Chen, He Wen, Baochuan Fu · 2022 41st Chinese Control Conference (CCC) · 2022
Aiming at the problems of smart grid economic dispatch (ED) that need to meet multiple constraints, slow dispatch speed and low dispatch accuracy, a distributed ED method is proposed that takes into account dispatch speed and precision. First, a smart grid system with distributed cooperative control is designed, and an economic dispatch problem model considering environmental benefits is established; Second, a distributed ED method combining distributed consensus algorithm with energy routers is proposed. It uses the leader-following consensus algorithm drive incremental cost convergence to main grid electricity price, it estimates the global power mismatch of the grid based on the average consensus algorithm, and it uses the energy router calculates the incremental power exchanged with the distribution system, so that the system gradually realizes the balance of power supply and demand; Finally, simulation results are presented to verify the effectiveness of the proposed method.
