Problems solved by technology

[0004] However, the active coordination control feature of the active distribution network control system makes it have a new impact on the power grid, and the existing index system is difficult to apply to the new characteristics of the active distribution network
Although the traditional system-side and user-side indicators can still evaluate the status of the distribution network, there is no reasonable and feasible evaluation standard for the control performance of the active distribution network itself.

specific Embodiment approach 1

[0068] Specific implementation mode 1, feeder planning

[0069] by Figure 4 The shown feeder planning problem of IEEEERBTS-BUS6 system F1 is taken as an example to illustrate the application of the present invention in feeder planning of active distribution network. The planning requires the addition of a feeder, which is used as a backup line under normal conditions and put into operation to ensure the reliability of power supply of the system in case of an emergency failure of the system. Figure 4 The illustration of components such as active control host, communication line, information collection mechanism and circuit breaker is omitted.

[0070] According to the planning method of the present invention, the active distribution network feeder planning is completed through the following steps:

[0071] Step 1, read in the network data of the area to which IEEE RBTS-BUS6 system F1 belongs; and according to the planning requirements, determine the type and parameters of t...

[0078] Specific implementation mode 2, microgrid grid-connected point planning

[0079] by Figure 5 The micro-grid grid-connection point planning problem of IEEE RBTS-BUS6 system F4 shown as an example illustrates the application of the present invention in active distribution network micro-grid grid-connection point planning. In the F4 system, the distributed power supply DG is added to the ends of feeder lines 29 and 30, so this area should be planned as a microgrid. Figure 5 The illustration of components such as active control host, communication line, information collection mechanism and circuit breaker is omitted.

[0080] According to the planning method of the present invention, the active distribution network micro-grid grid connection point planning is completed through the following steps:

Abstract

The invention discloses an evaluating method for a control system of an active power distribution network, and belongs to the technical field of control over the active power distribution network. The evaluating method uses a series of evaluating indexes for evaluating the control system of the active power distribution network, and the evaluating indexes include the equivalent operating cost in unit time CEAC, the redundancy RC, the control reliability CR, the control effect CE, the response sensitivity CS and the decision delay time CD. The invention further discloses a planning method for the active power distribution network based on the evaluating method. The current situation that evaluation analysis is insufficient in the aspect of the own control characteristic of the active power distribution network is changed; according to an evaluating index system set up in the evaluating method, a computing method is simple, the system content is comprehensive, economic benefits and technical benefits of the control system of the active power distribution network can be reflected fast and effectively, and powerful data support is provided for planning, operation and analysis of the active power distribution network.

Description

technical field [0001] The invention relates to an evaluation method for an active distribution network control system, belonging to the technical field of active distribution network control. Background technique [0002] The International Conference on Large Power Grids (CIGRE) proposed the concept of "active distribution network" in 2008, which brought the power system distribution network into a new stage of development. The main task of the distribution network of the power system is to directly supply electric energy to users. Since its goal is the distribution and use of electric energy, under the current condition that electric energy is an essential resource for life, the technological change of the active distribution network is of great importance to the daily life of the people and social stability. Harmony is essential. The goal of the active distribution network is to upgrade and transform the existing distribution network so that it can absorb as much diversi...
