Abstract

The invention relates to a new energy consumption time sequence simulation method based on regional decomposition iteration. A regional grid partition analogue simulation mixed integer optimization model and a whole-grid analogue simulation linear optimization model are constructed, and optimization calculation is performed to obtain the operation state of a partition generator set; the regional tie line transmission power and the new energy generation power are optimized and calculated on the basis of a partition unit operation state optimization result; and finally, iterative optimization calculation is carried out between the regional grid partition analogue simulation mixed integer optimization model and the whole-grid analogue simulation linear optimization model to obtain an optimalnew energy consumption result. A new energy consumption time sequence simulation basic principle based on regional decomposition iteration is determined, and corresponding detailed modeling and optimization calculation steps which can be realized by a computer are provided. A new energy consumption time sequence simulation method suitable for distributed calculation can be provided, so that the calculation efficiency is higher, the calculation speed is higher, and the method is more suitable for large-scale data calculation.

Description

technical field [0001] The invention belongs to the technical field of power supply, and relates to a new energy consumption timing simulation method based on regional decomposition and iteration. Background technique [0002] The energy supply model of excessive reliance on fossil fuels has brought global problems of resource shortage, climate change and environmental pollution, and the sustainable development of mankind is facing severe challenges. Based on the sustainable development strategy, the Chinese government attaches great importance to the development and utilization of new energy, and regards the development and utilization of new energy as a major measure to improve the energy structure, promote environmental protection, and maintain sustainable economic and social development, and regard wind power and photovoltaic power as new energy One of the main ways to develop and exploit. Due to the abundant wind energy resources in my country and the rapid development...
