Adaptive control technology for energy conversion process of photovoltaic energy driven ice storage air conditioning
In order to reduce the electricity load and improve the efficiency of photovoltaic energy utilization during peak hours,the adaptive control technology of photovoltaic energy driven ice storage air conditioning energy conver-sion process is studied.This technology is based on the operating principle of photovoltaic energy driven ice storage air conditioning.The characteristics of light electric energy conversion and transfer during the operation of the air conditioning as well as the flow situation are analysed,and the loss results of photovoltaic modules are calculated;The error and error change rate of the result are obtained,the results being used as input parameters for the improved fuzzy RBF neural network PID controller.The controller achieves adaptive control of the energy conversion process through adaptive adjustment of control parameters.The test results show that after the application of this technology,the energy conversion efficiency of air conditioning is above 55%,the energy efficiency is above 73%,and the ener-gy utilization rate during the ice making process of air conditioning is above 46%.This can significantly improve the energy conversion efficiency and energy utilization level;The electricity consumption during air conditioning opera-tion is below 3.22 kW/h;The load power has significantly decreased,varying within the range of 0.2~1.0 p.u.
