Abstract

The Combined Cooling, Heating and Power model (CCHP) is considered the foundation for forming an integrated network of different types of energy – including the Energy Hub (EH) model. This paper proposes and develops an operating strategy for an integrated model of many different forms of energy at a small scale, including electricity, natural gas, solar power, wind, storage, cooling, heating and particularly the waste heat generation system based on the Organic Rankine Cycle (ORC). The optimization problem is set up with a multi-objective function to minimize primary energy consumption and carbon emissions. Particle Swarm Optimization (PSO) algorithm is used to solve the problem of optimizing the operation of each element in the model. Finally, comparative analysis of the proposed model with the Micro grid (MG) is performed to show the advantages in saving energy and reducing emissions.
