分布式户用光伏与冰蓄冷空调协调控制研究

Research on Cooperative Control of Distributed Household Photovoltaics and Ice Storage Air Conditioning System

当前越来越多分布式光伏接入电网,一般情况下光伏发电与用电呈现出逆调峰特点.如何及时有效消纳光伏,本文提出光伏+冰蓄冷空调的消纳模式.根据光伏发电的随机性特点,结合冰蓄冷空调的工作特性,研究了太阳能发电和冰蓄冷空调的协调配合,对比分析冰蓄冷空调和普通空调的经济模型,得到光伏+冰蓄冷空调的经济效益.光伏+冰蓄冷空调的模式可以提高光伏消纳能力,达到削峰填谷的效果,减轻电网的供电压力.

At present,more and more distributed photovoltaics access power grid.Generally photovoltaic（PV）power generation and user power consumption have the characteristics of reverse peak shaving.In order to effectively consumptive PV problem,the paper proposes PV＋ ice storage air-conditioning consumptive mode.And then the coordination of solar power generation and ice storage air conditioning is studied according to the stochastic characteristics of PV power generation and the working characteristics of ice storage air conditioning system.Meanwhile,the economic model of ice storage air conditioning and general air conditioning is compared and analyzed;and then the economic benefits of PV＋ice storage air conditioning system are obtained.The mode of PV＋ice storage air conditioning can achieve the effect of peak shaving and valley filling,so as to reduce the operation pressure of the power grid.
