A transmission network planning platform with coordinated economy and security and its application

Abstract

The invention relates to an economic efficiency and safety coordinating power transmission network planning platform and application. The platform comprises a database module (1), an input module (2), an analysis module (3), a planning module (4), and an output module (5), wherein the database module (1), the input module (2), the analysis module (3), the planning module (4) and the output module (5) are sequentially connected; the input module (2) stores a safety index of a power transmission network, obtains the load data of the power transmission network, the data of power generation equipment and the data of power transmission equipment from the database module (1), and transmits the index and the data to the analysis module (3); the analysis module (3) calculates the investment cost, maintenance cost, operation cost and power shortage cost of the power transmission network, and transmits the cost to the planning module (4); the planning module carries out the extended planning analysis of the economic efficiency and safety coordination of the power transmission network through employing an improved ecological niche genetic algorithm; and the output module (5) outputs the information of planning results. Compared with the prior art, the platform enables the power transmission network to be low in comprehensive cost and to be high in economic benefit.

Description

technical field [0001] The invention relates to a transmission network planning platform, in particular to a transmission network planning platform with coordinated economy and safety and its application. Background technique [0002] Security and economy are two important factors to be considered in the planning and operation stages of power grids. Traditional power grid planning methods generally aim at the comprehensive minimization of investment costs, operation and maintenance costs, etc., and security factors are only added to the planning model as constraints (such as N-1 security constraints), so as to seek economic efficiency under a certain level of security. The optimal planning scheme, but this method cannot coordinate the contradictory relationship between power grid security and economy. In recent years, frequent large-scale power outages such as the 8.14 blackout in the United States and Canada have brought huge economic losses and social impacts to society, ...

AI Technical Summary

Problems solved by technology

At present, in the grid planning model, the security factor is generally considered in the constraints of the planning model, but not as a part of the planning goal, so it is impossible to achieve the coordination of security and economy in the grid planning stage.
