A Calculation and Modeling Method of Heating Power Adjustable Capacity of Heating Network

Abstract

The invention relates to a calculation and modeling method for the adjustable heating power of a heating network, and belongs to the technical field of operation and control of electric power systems with multiple energy forms. Based on the thermal dynamic simulation of the heating network, this method provides a calculation method for the adjustable heating power of the heating network, which can describe the flexibility of the heating network more accurately. The proposed heating power adjustable capacity model of the heating network has a concise and standardized form, and the parameters have clear meanings, which can be more widely used in the actual power system. This method can be applied to the online operation of the electric-thermal coupling multi-energy flow system. When the flexibility resources of the power system are not enough, the flexibility of the heating network can be used to adjust the heating power of the heating network and the power generation of the thermal power plant, which is beneficial Addressing the Adverse Effects of Renewable Energy Uncertainty on Power System Operations.

Description

Technical field [0001] The invention relates to a calculation and modeling method for the adjustable heating power of a heating network, and belongs to the technical field of power system operation and control containing multiple energy forms. Background technique [0002] With the consumption of fossil energy and the emergence of environmental problems, renewable energy has developed rapidly in recent years. However, many renewable energy sources are limited by natural conditions, and their electricity output has strong randomness and volatility, especially the predictability of wind power and photovoltaic power generation. As the power grid requires real-time power balance, a large number of uncertain renewable energy has brought great challenges to the safe and stable operation of the power grid, leading to a large number of wind and solar abandonment. At the same time, traditional thermal power generation will gradually decrease, leading to a gradual decrease in traditional ...

Problems solved by technology

However, there are still relatively few examples of using the flexibility of the heating network to improve the operation of the power grid. The existing examples also use relatively simple and rough methods, which cannot tap the potential of the flexibility of the heating network. One of the reasons is the lack of quantitative Calculation method and suitable model of heating power adjustable capacity of heating network
