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 analysis and technology of power systems, and in particular relates to a method and system for evaluating utilization efficiency of planned power grid schemes based on production and operation simulation. Background technique [0002] With the continuous expansion of the scale of the current power grid and the continuous increase in the proportion of power consumption in the terminal, the role of the power grid in optimizing resource allocation, ensuring energy security, and meeting the needs of economic and social development is becoming more and more obvious. In the past, power grid planning focused on the power grid. Electricity security, reliability, and high-quality supply requirements, while relatively little attention is paid to the efficiency of power grid operation. With the continuous deepening of the reform of the power system, the profit model of the enterprise is checked according to "reasonable cost p...
