There is an energy redundancy of the following electric load and following thermal load operational strategies, and an energy deficiency of the following hybrid electric-heating load. Thus an improved following balanced heat-electrical load operational strategy is proposed. Taking a hotel in the north as the research object, the installed capacity of the system is optimized with the goal of maximizing energy utilization rate. At the same time, an energy composite index is proposed, and the effects of purchased and redundant energy on system performance are investigated with five operating strategies. Also the supply and demand matching characteristics of the system using different strategies and the energy balance relationship of the system with the improved strategy proposed are analyzed. Finally, the role of the strategy in improving the system economy is explored through an arithmetic example, and a comparative analysis is conducted to verify the rationality and effectiveness of the study. The results show that, compared with the other four strategies, the energy utilization rate of the system with the improved strategy is increased by 4.3%, 4.38%, 4.75%, and 4.73%, respectively; the energy composite index is reduced by 6.58%, 5.96%, 2.23%, and 3.45%, respectively; and the total annual cost of the system is reduced by 11.65%, 2.74%, 1.64%, and 0.74%, respectively. The system’s supply-demand matching performance with the improved following balanced heat-electrical load strategy is optimum at 0.9382.
