Building energy management system of fusing demand responses and energy management method

The invention provides a building energy management system of fusing demand responses and an energy management method. The building energy management system of the demand responses includes a data acquisition unit, a data storage unit, a demand response unit, an energy saving strategy setting unit, a data analysis unit, a load forecasting unit and a control execution unit. According to the system and the method, strategy control is carried out on the basis of different situations through combining demand response management and energy saving management, a final energy saving proposal is given to a user according to actual situations, a most economical electricity consumption strategy is formulated, peak load shifting is realized, and electric charge expenditure is reduced. 本发明提供了种融合需求响应的楼宇能源管理系统和能源管理方法，需求响应的楼宇能源管理系统包括数据采集单元、数据存储单元、需求响应单元节能策略设置单元、数据分析单元、负荷预测单元、控制执行单元。本发明通过将需求响应管理和节能管理结合，基于不同情况进行策略控制，根据实际情况对用户给出最终的节能建议，制定最经济性用电策略，实现削峰填谷，减少电费支出。
