Abstract :
The conventional load density method that forecasts future demand divides the whole service area into a set of small areas, forecasting the load with single load simultaneity. Based on this load, the localities and capacities of substation equipments are planned. However, the result is that the capacities of low voltage (10 kV) substation are lower than the actual need, and the capacities of high voltage (220 kV) substations higher. To solve the problem, the concept of multi-level simultaneity and its forecasting models are introduced, and then a multi-level load system is constructed. The practical sample shows that the proposed method effectively solves the problems described above, and the matching between substation capacity and actual power needs in their respective localities is more rational.
