Abstract

The invention discloses an interval practical security domain modeling method, which is based on a regional comprehensive energy system containing renewable energy sources, considers the uncertainty of the renewable energy sources, and adopts an interval mathematical method for processing; by combining engineering practice, and based on the N1 security criterion of the regional comprehensive energy system and the load of an energy hub output side pipeline section, the method establishes an interval practical safety domain model of the regional comprehensive energy system containing renewable energy, further establishes an interval practical safety boundary model, and proposes an interval practical safety distance model and an interval maximum energy supply capacity model. On the basis, a system dimension reduction observation method and a full-dimensional observation method are established, and the safety of the regional comprehensive energy system containing renewable energy sources can be accurately and quickly analyzed.

Description

technical field [0001] The invention relates to the field of comprehensive energy systems, the field of security analysis of regional comprehensive energy systems containing renewable energy, and in particular to an interval practical security domain modeling method for regional comprehensive energy systems containing renewable energy. Background technique [0002] Energy is the source of power to promote the development of the national economy and ensure the survival and production of human beings. How to realize efficient, green and sustainable supply of energy is the focus of attention of all countries in the world. The concept of energy Internet and "Internet +" smart energy has been put forward, emphasizing the importance of cross-integration, diversification and common development of various energy sources in different disciplines. At the same time, the key technologies of energy conversion represented by combined cooling, heating, power, and gas-fired boilers have dev...
