As the cooling, heating and power system for traditional buildings ignores the energy storage characteristics and does not consider the participation of energy storage in decision-making, it cannot adjust the energy storage pressure, thus resulting in energy waste. Therefore, a hybrid load-following operation strategy considering energy storage characteristics is proposed in this paper. At the same time, in order to reduce the amount of model calculation and accurately select typical day of the load, a K-means clustering combined with CRITIC weighting is proposed. The system is optimized from three aspects: economy, energy and environment. The optimization results show that the K-means clustering algorithm with CRITIC weighting has higher contour coefficient and better clustering effect. At the same time, the comprehensive performance of the operation strategy proposed in this paper reaches 29.66%, which is much higher than the electric load following strategy and heat load following strategy. Compared with the traditional operation strategy, the proposed operation strategy has the best comprehensive performance, which verifies the feasibility and superiority of the proposed operation strategy.

Key words: building combined cooling, heating and power system, operation strategy, load typical day, CRITIC empowerment law, K-means clustering
