Abstract

PURPOSE:To provide a method and an apparatus for properly and easily obtaining supply validity which is an index for quantitatively appreciating adequacy of supply in each feeder for each node. CONSTITUTION:For determining a load interchange mode by assinging supply feeder to each node of the network as the load interchange object extracted by the processing block 101, a candidate feeder to each node is extracted in the block 102, a supply allowable capacity of each feeder to each node is obtained in the block 103, and supply validity which is an appreciation index of each feeder is obtained in the block 104 on the basis of the result of block 103. In the block 105, a supply feeder is determined for each node based on the supply validity of each feeder in the block 105 and it is checked in the block 106 whether there is no infringement on restriction in this determination or not. If there is no node which is not yet processed due to infringement on restriction, etc., the processing completes, but if there is such node, the network is set again in the block 108.

2. Description of the Related Art As a method of determining a load accommodation mode of a distribution system, a sequential solution method using heuristics as proposed in Japanese Patent Laid-Open No. 63-310333 has been put to practical use as software of a computer system. In the iterative solution method, since the feeder allocation process to each node is multistage in the process of determining the flexible mode, there is a problem that a large amount of calculation time is required especially when the target is large.

Therefore, as described in Japanese Patent Application Laid-Open No. 4-12625, all the systems are collectively searched for the supply validity which is a quantitative evaluation index of the supply suitability of each feeder that can be supplied to each node. A method and an apparatus for determining a flexible form have also been proposed. In this collective processing of all systems, it is important to accurately calculate the supply adequacy of each feeder for each node.

Supply density = (feeder reserve amount) / (total load amount of nodes having SLPs related to the feeder) (Equation 1) Supply distance = (feeder reserve amount−total relay nodes other than the target node) (Load amount) / (feeder reserve amount) (Equation 2) Here, the feeder reserve amount is a supplyable capacity of each feeder in a state where it is not accommodated in any node.
Details of SLP (Shortest Load Path) are disclosed in Japanese Patent Laid-Open No. 63-
Although it is handed over to 310333 and Japanese Patent Laid-Open No. 4-12625, the supply is defined so that the load amount of the node (relay node) on the way to each target node, which is defined within the range of the supply reserve amount for each feeder, is minimized. It is a route. Therefore, for each feeder, the existence of the SLP for the target node is a necessary condition for supplying it. On the other hand, from the node side, a feeder having an SLP to the node becomes a candidate for a feeder that can supply the node. In addition, S of the feeder
If the LP is branched, not all the nodes on the SLP can be supplied from the feeder within the range of the reserve amount. Therefore, the existence of the SLP to the feeder means that the node can supply by the feeder. ) It is not a sufficient condition.

The supply density defined by the equation (1) takes into account that the presence of SLPs is only a necessary condition for the feeder to be able to supply.
However, this only gives a rough evaluation of the supply candidate nodes for each feeder. For example, in the example shown in FIG. 2, the SLP of F1 is # 1 → # 2 → # 3 and # 2 → #.
The ends of 4 and # 2 are branched. Although the density value should be distinguished between # 1 and # 2 before branching and # 3 and # 4,

On the other hand, although the distance to the node of interest is defined by the equation (2), since it is normalized by the reserve amount of each feeder, for example, for # 2 in FIG. 2, F2 rather than feeder F1 is used. Has a higher degree of closeness (F1 → # 2:
