Operation Optimization of Integrated Energy System considering Power-to-Gas Technology and Carbon Trading

Algorithm 1

Main procedure of PSO.

	Algorithm main procedure of PSO
	Step 1: input load curve in the typical day, equipment operating parameters, and cost parameters
	Step 2: randomly initialize swarm population of particles
	Step 3: calculate the fitting function of each particle
	Step 4: update the velocity and position of particle
	Step 5: obtain individual fitness values and optimization parameters
	Step 6: iteration = iteration + 1
	Step 7: determine whether the iteration satisfies the maximum number of iterations, and output the best optimization result if it is satisfied; otherwise, return to step 2
