Description

TECHNICAL FIELD

[0001] The present application relates to the field of electric power, and in particular to a simulation system and method for mixed power grid and industrial load, a medium and an electronic device. BACKGROUND

[0002] In recent years, the penetration rate of new energy power generation represented by photovoltaic and wind power is continuously increasing. On the one hand, the rise of new energy promotes the development of new power systems, but on the other hand, its intermittency, randomness and volatility characteristics bring challenges to the stable operation of the power system. At the same time, with the increasing electrification of user terminal energy consumption fields, such as the popularity of electric heaters and electric vehicles, the demand for electricity on the load side is increasing year by year. The instability factors brought by new energy power generation on the source side are superimposed on the surge in demand for electricity on the load side, resulting in a tight balance between supply and demand in China's power supply, which restricts the development of new power systems, and flexible resources are urgently needed as an important support for their development.

[0003] High-energy-consuming industrial loads represented by cement, non-ferrous metals, and iron and steel have a large base, and their energy consumption accounts for more than 70% of the total industrial energy consumption, and their electricity consumption accounts for more than 28% of the total social electricity consumption. They have a large control potential and are high-quality demand-side resources that provide flexibility in the development of new power systems. As high-quality demand-side flexible resources, cement industrial loads can participate in various auxiliary services such as peak shaving and frequency modulation of the power grid, and provide flexibility to the power system in a tight balance between supply and demand, assisting the stable operation of the power system. However, the regulation capacity of cement industrial loads is affected by the comprehensive influence of process flow, energy supply mode, informatization level, and multiple uncertainties. The energy consumption and carbon emission characteristics are unevenly distributed in different links, and different links have complex energy coupling and time sequence correlation characteristics. In the process of participating in grid interaction, they may face problems such as increased energy consumption and operating costs, and even safety production hazards, which may reduce the willingness of cement production enterprises to actively provide demand-side flexibility.

[0004] In actual production, the uncertainty of load response may be caused by factors such as weather, price fluctuations, equipment failure, etc., and its randomness is caused by factors such as production planning, market price, unexpected situations, etc. However, in existing simulation research on the participation of cement industrial loads in grid interaction, there is a lack of comprehensive analysis of flexible interaction in multiple levels, multiple time scales, and multiple scenarios. SUMMARY

Through accurate data calculation, the production process can be optimized to reduce energy consumption and improve production efficiency and product quality. The cement plant simulation system adjusts the controllable load according to the peak shaving instruction and the operation data, and outputs industrial load time series simulation data. This real-time feedback mechanism helps to monitor and adjust the production process in real time, ensuring that production activities are consistent with the peak shaving instruction, thereby improving the response speed and flexibility of the entire system. The hybrid simulation system uses industrial load time series simulation data to perform simulation calculation and outputs power grid transient simulation data. This combination helps to evaluate and predict the impact of cement industry production activities on power grid transient stability, providing important reference for power grid operation. The simulation coordination management system sends the power grid transient simulation data to the cement plant simulation system for simulation of the production process. This coordination management mechanism helps to achieve close cooperation between the power grid and the cement industry, ensuring that production activities meet the needs of the power grid and meet the production goals of the plant itself. Strengthening the close cooperation between the power grid and the cement industry at multiple levels improves the flexibility and efficiency of the cement industry production process, while ensuring the safety and stability of the power grid operation.
