Two-stage multi-standby configuration method, system and device based on gas-heat inertia

Abstract

The invention discloses a two-stage multi-standby configuration method, system and device based on gas-heat inertia, and belongs to the field of comprehensive energy systems. According to the two-stage multi-standby configuration method based on the gas-heat inertia, the complex coupling relation among the gas-heat inertia power support size, the continuous input time and the continuous correction time of the comprehensive energy system is considered, and the gas-heat inertia standby unified model of the comprehensive energy system is constructed in combination with the actual standby configuration condition of the comprehensive energy system; gas inertia standby, thermal inertia standby, power generation side standby and demand side standby are comprehensively considered, the minimum total cost of system standby configuration in a two-stage scheduling period is used as a target function of comprehensive energy system standby configuration, and day-ahead constraint, intra-day constraint and day-ahead and intra-day correlation constraint are included at the same time. And the actual park-level comprehensive energy system is subjected to standby configuration optimization, so that the operation economy of the system is improved on the premise of ensuring the reliability level of the system.

Description

technical field [0001] The invention relates to the field of integrated energy systems, in particular to a two-stage multi-standby configuration method, system and device based on gas-thermal inertia. Background technique [0002] In recent years, the world's energy crisis and environmental pressure have prompted the continuous development of integrated energy systems, whose multi-energy complementary characteristics can help improve energy utilization efficiency and promote new energy consumption. But at the same time, the multi-energy coupling of integrated energy increases the complexity of system operation. Therefore, it is necessary to study the optimization of backup configuration of integrated energy system in depth to deal with the uncertainties of various sources and loads in system operation. [0003] However, the current technology focuses on the research on the backup configuration of large power grids, while the research on the backup configuration of integrated...
