Research On Automatic Demand Response System For Intelligent Building Electricity

With the rapid growth of human energy demand,energy shortages and environmental problems have caused trouble around the world.Nowadays,energy conservation and emission reduction have become the basic consensus of people.As a kind of clean energy,power energy is attracting wide attention from all walks of life.It is well known that people's demand for electricity is rising year by year,and the imbalance between power supply and demand is widespread in the short term.How to effectively alleviate this contradiction and promote the full and efficient use of electricity is still the focus of the problem that needs to be solved.As an important part of grid energy consumption,intelligent buildings have a large number of decentralized controllable load resources.With the development of smart grid technology,they can be concentrated through demand-side management and their resource potential can be deeply exploited.The automatic demand response technology is mainly aimed at the power user group.Through different tariff mechanisms or incentive models,users are motivated to guide users to actively adjust their power consumption behavior or power consumption time to achieve controllable load reduction within a specific period of time.The application of demand response technology to the use of electricity by building users can not only help the grid system to reduce the peak load adjustment load characteristic curve,but also effectively reduce the user's electricity cost.Based on the application of the principle of automatic demand response in the electrical environment of intelligent buildings,this paper designs a smart interactive terminal for the user application scene of intelligent buildings through the construction of demand response system and related analysis.The load reduction strategy of automatic demand response for power supply which takes into account the comfort of users is developed.Based on the analysis of the business process and the main functions of the automatic demand response system,this paper puts forward the specific conceptual model of the system.The response patterns and characteristics of the system are analyzed in detail with the information interaction between the system participants.In order to realize the overall functional requirements of the system,the hardware and software design of the intelligent interactive terminal is completed.According to the load classification and model construction of intelligent building users,an intelligent power dynamic priority and load reduction control algorithm based on the premise of satisfying the user's comfort level is proposed,and an automatic power control scheme for users participating in demand response projects is designed.The feasibility of this study in improving the load curve and reducing the user's electricity consumption is proved by an example.Figure[54] table[5] reference[60].
