全年不同负荷运行下的冰蓄冷空调控制策略

冰蓄冷空调一般用冰作为储能介质,在供电谷段制冰蓄冷,在供电峰段融冰释冷来满足用户冷负荷需求,对电网可以起到削峰填谷的效果。以冰蓄冷空调为主要研究对象,在不影响用户温度舒适度的前提下,通过分析空调在不同负荷下的蓄冰量、制冷机组功率以及响应潜力的变化,提出了一种全年不同负荷运行的冰蓄冷空调控制策略。在仿真算例中通过将冰蓄冷空调调控前后的蓄冰量、制冷机组功率和响应潜力进行对比,验证了该控制策略可以有效地降低用户运行费用,增加响应潜力,验证了此策略的可行性和有效性。

Control Strategy for Ice Storage Air Conditioning under Different Load Operations Throughout the Year

An ice storage air conditioning generally uses ice as an energy storage medium to manufacture ice and store cold in the valley of power supply and melt ice and release cold in the peak to meet the user's cold load demand.As a re?sult,it can cut peak and fill valley for the power grid.In this paper,the ice storage air conditioning is taken as the main research object.Under the premise of not affecting the user’s temperature comfort,the changes in ice storage capacity,refrigeration unit power,and response potential of the air conditioning under different loads are analyzed,and a control strategy for the ice storage air conditioning is proposed under different load operations throughout the year.Based on a simulation example and by comparing the ice storage capacity,refrigeration unit power and response potential before and after the regulation,it is shown that the proposed control strategy can effectively reduce the user’s operation cost and increase the response potential,thus verifying the feasibility and effectiveness of the novel strategy.
