1、 Background
▶National policy requirements
The "12th Five Year Plan" and the "Electricity Demand Side Management Measures" jointly issued and implemented by six ministries including the National Development and Reform Commission all explicitly state that "electricity demand side management is an important measure to achieve energy conservation and emission reduction goals".
▶Requirements for the construction of smart grid
Smart grid has become the development direction of the power industry, with several links including generation, transmission, transformation, distribution, and utilization. Demand side management system, as an important component of smart electricity, provides data support for auxiliary smart electricity related businesses.
▶Technical support requirements for demand side management of electricity
It can improve the safety, stability, and economy of the power system, while achieving two-way interaction between power supply companies and electricity customers, enhancing the reliability and service level of power supply, and increasing customer satisfaction.
2、 Overview
The demand side management system (DSM) monitors multiple energy monitoring areas in real-time to obtain energy data information for each monitoring area. By using a management system to improve the energy-saving rate of electrical energy, and under the premise of meeting product production conditions, reducing the power of equipment in each monitoring area, providing scientific means for energy management and conservation, quantifying the energy-saving goals of management itself, reducing the energy consumption of unit products, and improving comprehensive economic benefits.
Today, with the continuous development of technology, producers themselves are also required to keep up with the times; To enhance self and corporate awareness of energy conservation and environmental protection while continuously developing; Reducing energy consumption ensures energy conservation and emission reduction for enterprises, while also reducing their costs in daily production and operation.
