Problems solved by technology

Its advantages are mainly clear thinking, easy to use, and low requirements for calculation tools; the disadvantages are: 1. It only analyzes the impact of failures without considering the probability of failures, which may cause excessive investment; 2. It cannot handle the problems in power grid planning well. Uncertainties
With the restructuring of the power industry structure and the continuous development and improvement of the power market, probabilistic planning criteria have also been rapidly developed and applied due to their good performance in dealing with uncertain factors. The statistical data, and the randomness of the statistical data itself will affect the accuracy of the calculation

Embodiment

[0174] The present invention takes the power transmission network in the south of Jiangxi Province as the research object, simulates and calculates its medium-term planning scheme for the next ten years, and verifies the effectiveness and economy of the proposed method.

[0175] figure 2 It is a 500 / 220kV power grid in the south of Jiangxi Province. The test system has 22 nodes and 4 circuits of 500kV transmission lines. The maximum number of circuits that can be built for each channel is 3 circuits. Table 1 lists the relevant parameters of the line in the system. Table 2 shows the capacity of each generating unit and the initial load of the load node. Note: each load is divided into 5 areas equally according to the load size, and 5 power purchase prices are given at the same time; and the output of each generator is is a whole area, and the power supply price is a single value. Table 3 shows the parameters of different scenarios, for example: the proportion index of scenar...

Abstract

The invention relate to a hybrid planning method for medium-and-long term power transmission network expansion plan in an electricity market environment. The method includes a step 1 of setting a target function of a hybrid planning model; a step 2 of setting basic constraint conditions for power grid operation; a step 3 of detecting a power grid by utilizing an N-1 mandatory constraint condition and an N-2 flexible constraint condition; a step 4 of judging whether specific reliability constraint conditions are needed for enhancing the power grid so as to enable the power grid to meet the N-1 mandatory constraint condition and the N-2 flexible constraint condition; a step 5 of searching an optimal planning scheme for simulation calculation. The technical scheme provided by the invention can provide new evaluation indexes, new target functions and more reasonable and comprehensive reliability and economy constraint conditions for medium-and-long term power transmission network expansion plan. The method has characteristics of simpleness, practicability, comprehensiveness and high operability.

Description

technical field [0001] The invention relates to a power system planning method, in particular to a hybrid planning method for mid- and long-term transmission network expansion planning in an electric power market environment. Background technique [0002] With the further deepening of my country's electricity reform and the rapid development of the electricity market, power generation companies and grid companies are facing new challenges and opportunities. The rise of the electricity market has also brought new features to transmission network expansion planning. The main purpose of establishing the electricity market is to break the monopoly of the power system by introducing new participants and competitors in the power industry, to achieve the purpose of optimizing the combination and allocation of resources in the power industry, and improving the operating efficiency of the power system. The expansion planning of the transmission network not only needs to take into ac...
