Embodiment Construction

[0046] see figure 1 , the high-penetration distributed renewable energy generation cluster division method in this embodiment is carried out according to the following steps:

[0047] Step 1. In the active distribution network composed of distributed renewable energy power sources, loads and distribution lines, the busbars where distributed renewable energy power sources and loads are connected individually or both are called nodes; node characteristic matrix X is: X={X 1 ,X 2 ...,X N} T , N is the number of nodes to be divided into clusters in the distribution network, X i is the feature vector of node i, which is composed of the power characteristic curve of node i, the geographical coordinates of node i and the electrical distance vectors between node i and all nodes, i is a positive integer, and i=1,2...N.

[0048] The power characteristic curve of node i is numerically denoted as P i,1 ,P i,2 …P i,24 , P i,t is the node power of node i at time t on the hour of a ...

Abstract

The invention discloses a high permeability distribution type renewable energy generating cluster dividing method, which comprises the steps that distribution type renewable energy power supply, load,and distribution line form an active power distribution network, and the distribution type renewable energy power supply, and a bus accessed by the load are used as the node, and the dividing of thegenerating cluster can be conducted based on the proper phasor; the characteristic vector is formed by a node power characteristic curve, a node geographic coordinate, and node electrical distance; the hour node power curve at a typical day is used as the characteristic curve of the node power; the geographic plane coordinate of the node is used as the node geographic coordinate; the voltage wattles sensitivity matrix among nodes can be calculated based on network topology and the typical day load curve; fuzzy clustering algorithm can be adopted to construct a similar matrix based on differentcharacteristics of characteristic vectors, and the distribution type renewable energy power supply generating cluster dividing can be conducted. The invention is advantageous in that the regulation and control problem of large scale renewable energy can be simplified, and the group regulation and ground control of the renewable energy can be benefited.

Description

technical field [0001] The invention relates to the field of distribution network planning and control with distributed renewable energy sources, more specifically, a method for grouping high-permeability distributed renewable energy sources in the distribution network. Background technique [0002] After the distributed renewable energy power is connected to the distribution network, it has a huge adverse impact on the reliability and stability of the traditional distribution network. With the gradual increase of the penetration rate of renewable energy power in the distribution network, the complexity of the power grid and the difficulty of management and control faced by the distribution network also increase. Distributed renewable energy power is planned and managed in the form of power generation clusters, which can effectively solve the problems of orderly, safe, reliable, flexible and efficient access to the power grid for renewable energy power, and can achieve frien...
