<p>This paper discusses the feasibility and the optimal design of hybrid renewable energy generation system under electric load and thermal load in a severe cold region of China. This paper intends to use HOMER Pro software to evaluate the technical, economic, and environmental feasibility of the hybrid energy system with thermal load controller (TLC) schemes of a village in Jiamusi and to optimize the system capacity. This study considers the effect of ambient temperature on the considered system. The Load Following (LF), Cyclic Charging (CC), and Predictive Scheduling (PS) control strategies are used in the simulation design. Results indicate that the proposed WT/PV/Battery system is economically viable for the village under both electric load and thermal load over the life of the project. Most of the village’s electricity supply comes from PV power, while another portion comes from wind power. Moreover, most of the village’s heat comes from the TLC, and a portion of the heat is provided by the generic boilers. At the same time, the environmental comparison study on the presence&#xa0;of TLCs in the power generation system shows that the emissions of all the power generation systems with TLCs are lower than those without TLCs.</p> Graphical abstract <p></p>
