Power Supply Capacity Calculation for Urban Distribution Network Based on Load Forecast
This paper presents a power supply capacity calculation method for urban distribution network based on load forecast,whereby the prediction model is employed to obtain the load growth mode.First,determine the optimal prediction model according to the historical data; then successively apply the forecast data for flow calculation until the first off-limit occurrence; finally,locate the critical point as the precision requirement using the bisection method.Actual examples show that the method,clear in logic and simple in calculation,can not only improve the precision,but also find out the bottlenecks of limiting the actual load growth,providing effective reference for urban distribution network planning and improvement.
