Abstract

Abstract: ABSTRACT： In recent years, microgrids with renewable energy generation as well as combined heat and power systems (CHPs) have been widely applied in many industrial fields due to favorable economic and environmental characteristics. Some loads in an industrial microgrid are flexible and controllable, which can be employed as a kind of potential dispatchable resources. In the operation of an industrial microgrid, how to fully employ these controllable loads and implement coordinated optimal dispatch among generators and loads are the key to improve the operation efficiency of microgrids and promote the accommodation capability of renewable energy generation. Given this background, a framework of a CHP embedded industrial microgrid is first presented, with multiple kinds of controllable loads and renewable energy generation included. Then, detailed models of three kinds of controllable loads, namely industrial manufacturing devices, heat ventilation and air conditioning (HVAC) and electric vehicles (EVs), are formulated respectively. On this basis, an optimization model with an objective of minimizing the energy cost in an industrial microgrid is developed and then solved through the CPLEX commercial solver. Finally, a case study is conducted in a typical industrial microgrid to demonstrate the feasibility and effectiveness of the proposed model.

Key words: controllable loads, generation-load coordination, industrial microgrid, industrial manufacturing device, electric vehicle
