Dynamic adjustable potential analysis method and system for heat storage and supply system

Abstract

The invention discloses a dynamic adjustable potential analysis method and system for a heat storage and supply system. The method comprises the following steps: predicting output of a photovoltaic generator set and predicting output of a wind power generator set; establishing a general mass, energy and momentum conservation model for heat storage and supply, and establishing a general pipeline outward heat release model, a heat release coefficient model and a general pipeline metal wall heat balance model; establishing a heat supply pipe network heat storage capacity potential analysis modelthrough the above models; establishing a heat storage capacity potential analysis model for the heat storage device storage and release multiplying power to obtain the dynamic adjustable potential ofthe heat storage and supply system; feeding the predicted output of the photovoltaic generator set, the predicted output of the wind power generator set and the dynamic adjustable potential of the heat storage and supply system back to a power dispatching center, so that the power dispatching center adjusts the output of the heat storage and supply system. Thus, renewable energy output is consumedto the maximum extent, the heat load requirement of users is met, and interaction between the heat storage and supply system and a power grid is achieved. According to the method, new energy consumption is promoted, and the requirement for safe and stable operation of a power grid is met.

Description

technical field [0001] The invention relates to a dynamic adjustable potential analysis method and system of a heat storage heating system, belonging to the field of heating systems of comprehensive energy systems. Background technique [0002] Energy is the basis for the survival and development of human beings and the lifeblood of national economic development, and the energy consumption of buildings accounts for 25%-35% of the total energy consumption. Among them, building energy consumption is mainly manifested in the form of heating and cooling of buildings. How to make full use of renewable energy on the basis of ensuring that the thermal load demand is met, and cooperate with the precise load shedding of the power grid to reduce the impact on the power grid is a common concern of scholars and researchers from all over the world. Because traditional fossil energy sources such as coal, oil, and natural gas are non-renewable, discovering new energy sources, carrying out...
