Optimization Allocation And Benefit Analysis Of Energy-intensive Enterprises Microgrid Based On Load Control

The 13 th Five-year Plan has adjusted the China’s economic growth rate development goal to the tolerance range of “Carbon emission quota” and ecological red lines. Therefore, energy-intensive enterprises urgently needs to accelerate the industrial development model transformation, make efforts to achieve energy saving and consumption reducing goal, increase the new energy utilization. In recent years, the Microgrid technology has been put forward in domestic China and oversea, which is a new energy network management technology. It can help to realize the demand side management and the maximum utilization of renewable energy and other resources. Thereinto, load control technology is the main part of power demand side management, which adjusts the load of demand side through the technical means, economical meatures and other incentives. It promotes the load rate of power supply and enhances the reliability of the system.Focused on the urgent need of energy-intensive enterprises to accelerate the transformation of industrial development mode, a wide range of study is taken on the demand side. Firstly, it optimizes the typical process load in energy intensive enterprises by using PSO to reduce the energy consumption on basis of traditional energy saving technology. Secondly, Ensuring that the regular production of energy-intensive enterprises are not affected, the scheduling of Transferable load is adopted, which is regarded as a new energy for active participation in microgrid planning to improve the energy efficiency of enterprises. Finally, it utilizes the load control method to realize the microgrid planning optimal energy allocation for the purposes of reducing greenhouse gas emissions and minimizing the pollution. The main contents of this paper include:(1) Focusing on the energy-intensive enterprises microgrid which consists of distributed energy, load, large power grid and Energy storage system. It analyzes the overall structure of microgrid, mathematical model of each component and technical characteristics and introduces the simulation platform software. It also arranges the demand side load transfer scheduling as energy which takes an active participation into the microgrid planning by considering the economical, environmental and renewable energy penetration indexes in the optimization of micro grid energy planning.(2) Firstly, It introduces the classification of the demand response, and the influence of its incentives on energy-intensive enterprise. Secondly, it summarizes load classification of energy intensive enterprise and characteristics of the electricity, therein, which analyzes in detail a typical demand response based production processes for load reduction. Finally, it will optimize the load of typical operations by using PSO and make reasonable distribution and energy optimization to achieve the goals of energy-intensive enterprise energy optimization.(3) Considering the basic electricity cost in energy saving and energy-intensive enterprises, it puts forward a new method which controls the power demand based on the load transfer scheduling energy-intensive enterprises. The verification results shows that this model has a good load scheduling effects, which can enhance the power demand control of the energy-intensive enterprises.(4) Aimed at energy-intensive enterprises microgrid, it adopts the power load control method to realize the microgrid optimal energy allocation and optimal energy benefits. Firstly, it processes the transfer load of the demand side as a new energy for active participation in microgrid planning and select the optimum energy allocation. Secondly, it optimizes the load of typical operations by using PSO and makes reasonable distribution and energy optimization. Finally, it analyzes the energy efficiency and environmental benefits bought by load control method.
