Comprehensive energy station planning method and system for power generation and gas production from renewable energy

Abstract

The invention discloses a comprehensive energy station planning method and system for power generation and gas production from renewable energy. The planning method comprises the following steps: inputting energy supply and demand information of a comprehensive energy station to be planned; establishing a comprehensive energy station planning model for power generation and gas production from renewable energy; and respectively establishing uncertainty-considered random distribution models of wind power, photovoltaic power, electrical load and natural gas load, establishing planning constraintconditions, determining a planning problem, solving the planning problem, and outputting a solving result including equipment type selection and capacity configuration schemes thereof and annual comprehensive cost of the comprehensive energy station. By utilizing the characteristic that natural gas is easy to store, surplus renewable energy is subjected to power generation so as to be completely converted into natural gas and other clean energy, full consumption of renewable power generation and safe and stable operation of a power grid are achieved, the natural gas and other forms of clean energy are provided, the requirements of different users are met; and diversity and safety of energy supply are guaranteed.

Description

technical field [0001] The invention relates to the technical field of planning of an integrated energy system, in particular to a method and system for planning an integrated energy station for generating gas with renewable energy. Background technique [0002] Renewable energy generation such as photovoltaics and wind power does not pollute the environment and meets the development needs of the national energy strategy. With the gradual reduction of its power generation cost, it has been widely used in power grids at all levels. However, the inherent volatility and randomness of renewable energy power generation have a great impact on the safe and stable operation of the power grid, and in some areas, due to the limited capacity of the power grid, the phenomenon of abandoning wind and light is common, which seriously affects the renewable energy. Economic and social benefits of energy power generation. At the same time, the society's demand for other clean energy represen...

However, the inherent volatility and randomness of renewable energy power generation have had a great impact on the safe and stable operation of the power grid, and in some areas due to the limited capacity of the power grid, the phenomenon of curtailment of wind and light is common, seriously affecting renewable energy. The economic and social benefits of energy power generation

At the same time, society's demand for other clean energy represented by natural gas has increased sharply, but at present, a considerable part of my country's natural gas consumption depends on imports from abroad, which has a negative impact on my country's energy supply security
