Capacity planning method for comprehensive energy system containing intermittent new energy

Abstract

The invention discloses a capacity planning method for a comprehensive energy system containing intermittent new energy. Based on annual historical data of wind and light intermittent new energy and electricity, heat and gas loads, scene generation is carried out by considering coupling characteristics among the electricity, heat and gas energy, and a typical scene set for processing uncertain factors of wind and light intermittent new energy output and the electricity, heat and gas loads is formed; a two-layer capacity collaborative planning model for minimizing the investment operation costof the electricity-heat-gas comprehensive energy system containing wind and light intermittent new energy and various energy coupling devices is constructed; and the two-layer capacity collaborative planning model is solved to obtain a capacity planning scheme of each device in the electricity-heat-gas integrated energy system, and the effectiveness of the capacity planning scheme of the electricity-heat-gas integrated energy system containing intermittent new energy is verified. The method gives full play to the complementary characteristics of various types of heterogeneous energy, achievesthe coordination and unification of the planning process and operation process of the integrated energy system, and improves the comprehensive utilization efficiency of energy.

Description

technical field [0001] The invention relates to a capacity planning method of an integrated energy system. In particular, it relates to a capacity planning method for an integrated energy system containing intermittent renewable energy. Background technique [0002] Energy and environmental issues are currently a huge challenge for all countries in the world. Renewable resources such as wind power and solar energy are clean and environmentally friendly, and they are an effective way to develop low-carbon electricity and deal with global warming. However, the intermittence, volatility and uncertainty of renewable resources such as wind and rain have brought great difficulties to their consumption and utilization. How to efficiently utilize these intermittent new energy sources has become an urgent problem to be solved. [0003] The integrated energy system breaks the pattern of separation between different energy supply systems, and realizes the integration and coordinated s...
