Economic Dispatch for Integrated Energy System Based on Improved Dragonfly Algorithm
In order to improve the economic benefits of the Integrated Energy System(IES)that encompas-ses heat,electricty and gas,this paper constructs an economic dispatch model for the IES with the objec-tive of minimizing the total cost.The improved Dragonfly Algorithm(IDA)is improved by incorporating in-verse chaotic mapping and nonlinear inertia weights to enhance its optimization performance.By applying the IDA to solve the economic dispatch model of the integrated energy system and comparing the results with those of commonly used optimization algorithms,it is showed that the IDA has better optimization effects in the economic dispatch for the integrated energy system.Under this dispatch scheme,the output of each equipment is rationalized and the total cost of IES is also minimized,achieving the economic dispatch for the IES.
