This paper proposes the definition, model and algorithm of two quantitative indices named the Total Supply Capability (TSC) and Ideal Total Supply Capability (ITSC) for distribution planning. The TSC of a distribution system is comparable to Total Transfer Capability (TTC) in transmission systems, which is defined as the maximum load it can serve under the N-1 guideline for distribution systems, taking...
The computer-supported decision-making system has become an essential tool for the sustainable growth and expansion planning of modern urban power distribution network. Current packages with planning functions are independent packages, which are limited in the academic research. Presently, in Shanghai Municipal Electric Power Company and its subordinate units, a geographic information system(GIS)-based...
A proper evaluation on the power supply capability of urban distribution system is of enormous social and economical significance. In competitive marketing environment, to satisfy the sustainable growth of distribution loads, electric utilities must judge whether the return of power supply capability is sustainable and valued against the certain amount of investment. Therefore, to make up the insufficiency...
To adapt the needs of the rapid development and more frequent construction or reconstruction of urban distribution network in China, this paper proposes a comprehensive computer-supported planning software system, which is called planning platform. It is different from the traditional decision-making system which only plays a role as an analysis and decision-making support tool for planning engineers...
A calibration method for the medium/long-term load forecasting is presented. Firstly, a calibration model is built up, based on the regular pattern that the same trend is basically shared by the peak load and the maximum temperature. Secondly, a calibration method is presented. The first step is to correct the historical annual peak load and obtain the load which has no relations with the temperature...
Planning is vital for the development of power system; and the quality of planning has direct influence on security, reliability and economy of the power system in the future. Therefore, it is urgently needed to study quantitative evaluation method for distribution network planning. First, this paper proposes a practical comprehensive hierarchy and method on evaluation of distribution network planning...
