Abstract

The present invention discloses a distribution network planning method based on the industry load prediction technology. The method comprises a step of preparing data which comprises load information, substation alternate point position information, the construction cost of a unit line and a substation, unit load loss cost, unit line damage cost, the practical coefficient needed by the industry load prediction technology, and the database of a phase coefficient, a step of using the industry load prediction technology to predict a load point load based on a load point installation capacity, a step of completing a substation address selection working through a genetic algorithm population operation, and obtaining a selection point set, a step of completing the distribution of a load point based on the Voronoi diagram theory, and using the Monte-Carlo-based interval estimation to calculate line current and distribution substation capacitance, and a step of taking the total cost in a planning period as a minimum target function, calculating the target function, and outputting an optimal result. According to the method, the distribution network planning method is more close to an actual condition, the cost of actual distribution network construction operation is reflected, and a decision support is provided for the investment of the distribution network construction in a new situation.

Description

Technical field: [0001] The invention belongs to the field of power distribution network planning, and in particular relates to a distribution network planning method based on industry load forecasting technology. Background technique: [0002] With the development of cities, land resources in urban areas, especially urban areas, are becoming more and more scarce, and the construction cost of distribution stations is high, while the demand for electricity from users continues to increase, and the installed capacity of users has increased rapidly. On the other hand, the utilization efficiency of the distribution station is not high, and the distribution station whose interval has been opened is in a light-load operation state for a long time. According to the actual operation of the power company, the installed capacity of general users far exceeds the actual load, resulting in a relatively extensive 10kV power supply scheme for substations, and the utilization rate of substa...
