Description

Technical Field

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

[0002] In recent years, the penetration rate of new energy power generation represented by photovoltaic and wind power has continued to increase. On the one hand, the rise of new energy has promoted the development of new power systems. However, on the other hand, its intermittent, random and volatile characteristics have brought challenges to the stable operation of the power system. At the same time, with the improvement of electrification in the field of user terminal energy consumption, such as the popularization of electric heaters and electric vehicles, the demand for electricity on the load side has been rising year by year. The unstable factors brought by new energy power generation on the source side and the surge in user electricity demand on the load side have led to a tight balance between my country's electricity supply and demand, which has restricted the development of new power systems and urgently needs flexible resources as an important support for their development.

[0003] The high-energy-consuming industrial load represented by cement, nonferrous metals, and steel has a large base, accounting for more than 70% of the total industrial energy consumption, and more than 28% of the total social electricity consumption. It has a large potential for regulation and is a high-quality demand-side resource that provides flexibility in the development of new power systems. As a high-quality demand-side flexibility resource, the cement industry load can participate in a variety of auxiliary services such as peak regulation and frequency regulation of the power grid, provide flexibility to the power system in a tight balance of supply and demand, and assist the stable operation of the power system. However, the load regulation capacity of the cement industry is affected by the comprehensive influence of process flow, energy supply mode, information level and multiple uncertainties. The energy consumption and carbon emission characteristics are unevenly distributed in different links. Different links have complex energy coupling and time-series correlation characteristics. In the process of participating in the grid interaction, it may face problems such as increased regulation energy consumption and increased operating costs, and even bring safety production risks, which in turn leads to a decrease in the willingness of cement production enterprises to actively provide demand-side flexibility.

[0004] In actual production, the uncertainty of load response may come from multiple factors such as weather, electricity price fluctuations, equipment failures, etc., while its randomness comes from the influence of factors such as production plans, market prices, emergencies, etc. However, in the existing simulation research on cement industry loads participating in power grid interaction, there is a lack of comprehensive analysis of flexible interaction at multiple levels, multiple time scales, and multiple scenarios. Summary of the invention

The hybrid simulation system uses the industrial load timing simulation data for simulation calculation and outputs the transient simulation data of the power grid. This combination helps to evaluate and predict the impact of cement industry production activities on the transient stability of the power grid, and provides an important reference for the operation of the power grid.
