Method and system for evaluating utilization efficiency of planning power grid scheme

Abstract

The invention relates to a method and a system for evaluating utilization efficiency of a planning power grid scheme. The method comprises the following steps of 1) considering a power grid load growth rate and new production power equipment in the planning year based on pre-collected basic data of a current power grid, and forming a topological structure, a load vector and a power plant output vector of a planning year power grid according to a production sequence of the planning power grid schemes; 2) carrying out power grid production operation simulation through load flow calculation in order to obtain production operation simulation result data of the power grid under each planning power grid scheme; 3) calculating to obtain a power grid utilization efficiency evaluation index value of each planning power grid scheme according to the obtained production operation simulation data of each planning power grid scheme and a pre-established power grid utilization efficiency evaluation index; and 4) calculating an efficiency benefit improvement score of each planning power grid scheme, and evaluating different planning power grid schemes according to the score conditions in order toobtain a planning power grid scheme with the optimal efficiency benefit. The method and the system can be widely applied to planning power grid scheme evaluation.

Description

Technical field [0001] The invention belongs to the field of power system analysis and technology, and in particular relates to a method and system for evaluating utilization efficiency of planned power grid schemes based on production operation simulation. Background technique [0002] With the continuous expansion of the current grid scale and the continuous increase in the proportion of power consumption in the terminal, the role of the power grid to optimize resource allocation, ensure energy security, and meet the needs of economic and social development is becoming more and more obvious. The requirements for safe, reliable, and high-quality power supply, and relatively little attention to the efficiency of the grid. As the reform of the power system continues to deepen, the profit model of the enterprise is checked according to "reasonable cost plus permitted income", and the transmission income of the enterprise is calculated by multiplying the transmission and distributio...

Problems solved by technology

However, there are still few research results on the calculation of the utilization efficiency of the planned power grid, lack of scientific theoretical guidance and practical operation methods, and it is impossible to measure the utilization efficiency level of the planned power grid scheme, let alone realize the comparative analysis of the utilization efficiency of different planned power grid schemes
