Study of energy scheduling and optimal cost management of a new structure CCHP system: A case study supplying energy for a chemical enterprise in Jiangsu Province

A new structure combined cooling, heating and power (CCHP) system integrating green applying a control strategy based on improved whale optimization algorithm is proposed in this paper. This paper fully considers the high energy demand large amount of waste heat chemical enterprises. By absorbing (mainly from wastewater), coupling wind photovoltaic equipment, adding heating, electricity storage with an scheduling strategy, efficient CCHP for target enterprise realized. The used to optimize cost management. results show that after algorithm, meets higher efficiency at lower cost. In winter summer, pump recycling wastewater provides 15.4%–57.9% 11.5%–62.9% load network. Meanwhile, lithium bromide refrigerator cooling-net equipment average cooling 6.25–58.4% 7.01–16.64%.​ Finally, reduces total by 2.4 % 2.17 %.
