Carrying capacity evaluating method for intelligent distribution and utilization system

Abstract

The invention provides a carrying capacity evaluating method for an intelligent distribution and utilization system. The carrying capacity of the intelligent distribution and utilization system refers to the bearing capacity of power generation and load fluctuations of lines and equipment in a distribution network in the aspects of technical rationality, safe reliability, economy, environment, energy and capacity margin under the conditions of external social economy, environment and energy development, wherein the conditions support the development of a power grid. The method comprises the steps that according to the carrying capacity theory and the characteristics of the intelligent distribution and utilization system, an intelligent distribution and utilization system carrying capacity evaluation system is built, and various indicators of the carrying capacity of the intelligent distribution and utilization system are acquired; according to the characteristics of generalized distributed resources such as an electric vehicle, a distributed power supply, an energy storage system and a flexible load, the load curve of a generalized distributed resource charging station is given; and the relationship among various variables of the carrying capacity of the intelligent distribution and utilization system is analyzed to construct the system dynamics model of the carrying capacity of the intelligent distribution and utilization system. According to the invention, technical support and decision-making basis are provided for sustainable development of the intelligent distribution and utilization system.

Description

technical field [0001] The invention relates to a method for evaluating the carrying capacity of a power consumption system. In particular, it relates to a method for evaluating the carrying capacity of an intelligent power distribution and utilization system for generalized distributed resource access. Background technique [0002] Since the industrialization of human society in 1650, the extensive use of fossil fuels has emitted CO 2 The combined effect of greenhouse gases and other pollutants has led to the warming of the global climate system, which has further intensified since the middle of the 20th century and has become a major problem restricting the sustainable development of human society [1]. In recent years, the trend of global warming has become increasingly serious. [0003] Intelligent power distribution system is one of the key links in the construction of smart grid. The development of intelligent power distribution system will transform the distribution...

Problems solved by technology

[0006] The traditional distribution network does not contain distributed power sources, and there is no active control of power sources and loads. In the past few decades, the power system has developed into a large-scale interconnected network system with centralized power generation, long-distance power transmission, and extensive access to generalized distributed resources. The continuous growth of load, the aging of the power system structure, the increasingly serious environmental pollution, the low efficiency of energy utilization and the continuous improvement of users' requirements for power quality. Therefore, it is of great significance to carry out the evaluation of the carrying capacity of the intelligent power distribution system.
