摘要
In order to promote the renewable energy accommodation of insular island microgrid and reduce the load peak and off?peak difference. In this paper the islanded microgrid introduced price?based demand response，with minimized the cost of operation and diesel generator output as the objective function，considering the constraints of power balance，unit startup?shutdown and state change of pumped storage. A multi objective optimal operation mod el for insular island microgrid is established，and solved using crow search algorithm（CSA）. The simulation results show that the introduction of price?based demand response in the insular island microgrid can effectively reduce the load peak and off?peak difference，and the economic benefit is remarkable. Compared with the particle swarm optimi? zation (PSO) algorithm，the crow search algorithm has obvious advantages in the ability of convergence speed and global optimization.
