Research On The Characteristic And Response Potential Of Household Electric Appliance Load

As an important part of smart home,household electric appliance is a major modular in electric loads,at the same time it is measured by Home Energy Management System as an objective.It is of great significance to promote the interaction between power supply and demand and realize the comprehensive development of smart home,home automation by study the key technologies of household electric appliance management for smart grid.As the primary section of researching this technology,analyzing the characteristic and response potential of household electric appliance plays a key role in improving the characteristic of electric appliance,establishing the model about characteristic and response potential of this load and better boost the development of smart grid.Based on the measured data,characteristic of electric appliance load,electrical behavior,and the response potential of electric appliance are discussed by using some science field methods consist of analyzing the curve and correlation and Entropy in this paper.The research is as follows:First,on the basis of the study in China and abroad,combined with the field investigation and collection of the electric data,discussing the change in electric load which influenced by two non-electrical factors is weather and social life,studying the change about characteristic in electric load which affected by two electrical elements is the different household electric equipment and susceptibility facing the different power price,analyzing the run low in three loads of the typical household electric appliances which is the air conditioner,heater and the fridge in this paper.In second,presenting the concrete link and procedure about the behavioral analysis of power users under the smart household electricity background,building the characteristic model of the electrical behavior by using the relation analysis method in full consideration of some factors including the mutual cooperation between different household electric appliances,the comfort degree in power users,the different transfer time of individual household electric appliance loads and the preference and habit in using the household electric appliance by people,discussing the characteristic of the electrical behavior in group household electric appliance under the above model based on case and proving the good practical result in this model by analyzing the curve of load,establishing the Markov Chain electrical characteristic model reflecting the relationship between electrical behavior and electrical demand in group of different influencing factors and the practicability of this modelis verified by investigating and analyzing the field data,this model considering the influence of different factors on household electric appliance and the influence of different users on electrical demand.Last,the different load form of composition between the different household electric appliance are elaborated in detail,the impact of some index system which are response rate,response duration,electrical time,adjustable ability of electricity and the power price susceptibility on response potential of electric appliance is deeply researched aiming at the different load form of composition.
