Joint response regulation method of coping with climate changes by urban water system and energy system

Abstract

The invention provides a joint response regulation method of coping with climate changes by an urban water system and an energy system. The method includes: collecting temperature information and precipitation information, and obtaining a future precipitation quantity change trend and a future temperature change trend; establishing a water resource evaluation model of a study area; establishing along-term energy-substitutable planning model of the study area; predicting electricity use quantity and water demand quantity according to the future temperature change trend, and predicting water supply quantity according to the future precipitation quantity change trend; inputting the water supply quantity and the water demand quantity into the water resource evaluation model for water resources optimization arrangement under different emission scenes; running the long-term energy-substitutable planning model according to water resource optimization arrangement results to calculate and obtain power consumption quantity of a water supply industry; and calculating and obtaining energy consumption quantity according to the electricity use quantity and the power consumption quantity of thewater supply industry. The method provides a more accurate basis for study of the urban water system and the energy system.

Description

technical field [0001] The invention relates to a joint response control method for urban water systems and energy systems to cope with climate change. Background technique [0002] Cities expand their metabolism by absorbing various resources in the ecosystem. According to the report of the International Energy Agency, more than 70% of the world's energy consumption occurs in cities. With the global urbanization process, the demand for energy will greatly increase in the next ten years . At the same time, water resources are also a major constraint factor restricting urban development. It is estimated that by 2050, 75% of the world's population will face a crisis of lack of fresh water resources. How to ensure sustainable fresh water resources and energy supply in the face of global climate change is a huge challenge in the process of global urbanization. Therefore, it is of great significance to study urban water system and energy system to cope with climate change. [...

AI Technical Summary

Problems solved by technology

[0003] At present, scholars at home and abroad are more inclined to consider the impact of climate change on water resources or energy systems separately, and the formulation of countermeasures is usually only for one system. For example, in order to alleviate the shortage of water resources under climate change, the introduction of high energy-consuming seawater Desalination technology puts greater pressure on the energy system, increases greenhouse gas emissions, and has a negative impact on climate change
