Problems solved by technology

These existing technologies provide meaningful exploration for the establishment of power grid evaluation index system, and their ideas are very worthy of reference, but the disadvantage is that they are often limited to the current power grid security evaluation, and do not fully estimate the future development trend and faults. risk, or mainly focus on the development, operation and planning of the power grid, the security of the power grid needs to be enhanced, so it is necessary to provide a method to apply the index system to the actual power grid

Embodiment

[0100] In the actual scheduling system, its specific implementation steps are as follows: figure 2 As shown, first the indicator calculation module judges whether the specified calculation cycle has been reached, if not, it continues to wait, otherwise, it starts to send the corresponding message number (including: current state message number 0, future state message number 1, risk state message number 2) For each indicator calculation module; when the indicator calculation is manually started at any time, the message number will be sent immediately. Each index calculation module starts to calculate the index of the corresponding mode after receiving the message: 1) The index calculation of the current state is relatively simple, only need to obtain the current data of the power grid, and the calculation can be completed, the calculation amount is small, and can be completed on one machine; 2) The future state takes the power generation plan data and load forecast data at N t...

Abstract

The invention relates to a grid security comprehensive index system constructing method. The method comprises the following steps: 1) selecting n grid security basic indexes; 2) constructing a grid security comprehensive index system comprising five grades of index layers; 3) carrying out calculation on weight of the n grid security basic indexes under a grid security comprehensive index by utilizing an analytic hierarchy process; and 4)carrying out aggregation on the grid security basic indexes by utilizing the basic index weights to obtain the grid security comprehensive index. The grid security comprehensive index system constructing method, starting from constructing a grid security index system, strives to enable current state, future state and risk state to be combined, and current and future development tendency and fault risk conditions of grid operation are evaluated in an all-round multi-angle manner, thereby effectively assisting scheduling operation personnel to finish grid operation control.

Description

technical field [0001] The invention relates to an architecture method in the field of electric power technology, in particular to an architecture method for a grid security comprehensive index system. Background technique [0002] With the continuous expansion of the scale of the power grid, the complexity of power grid operation continues to increase, and the security issues of the power grid are becoming more and more prominent. Dispatchers not only need to monitor the real-time security of the power grid, but also assess the future security risks of the power grid in advance in a longer period of time. In recent years, natural disasters such as ice disasters and earthquakes have occurred frequently, and the operating conditions under extreme natural disasters have increased the difficulty of monitoring and control by dispatchers to a greater extent. In order to improve the scientific dispatching level of the power grid dispatching department and the ability to control th...
