Design And Application Of Power Short-term Load Forecasting System

In the real work of load forecasting, accuracy directly affect the efficiency of electric energy. Load forecast is accurate or not, is the electric power department assessment is an important indicator of power. Power load forecasting in algorithm has been quite mature in theory, but can not achieve the desired effect in the actual production, the reason is that there are many factors which can influence power load, which requires the power sector should start from the most basic section of the power load, refine prediction step by step, and then, eventually forming prediction curve, it needs to consider the effect of regional, but also consider the effect of factors such as maintenance power outages. Therefore, this topic embarks from the actual production situation of power system, development of Da Zhou power short-term load forecasting system.This article obtains from the related concepts of power short-term load forecasting, the research status and development trend were detailed research and analysis, expounds the research of short-term load forecasting for electric power production significance and meaning; Then to the present stage electric power short-term load forecasting system made a careful study of the commonly used algorithm, discusses the theory of a variety of algorithms, and has carried on the induction classification of some typical algorithms; Secondly combining Da Zhou the geographic location and economic and social development of the region, comprehensive consideration of various conditions of power load demand situation, to establish the power short-term load forecasting system demand analysis, according to the modular thought has carried on the detailed functional division of the whole system; Finally completed under the support of Da Zhou power short-term load forecasting system development work, realize the various functions of demand analysis, and applies the system to the actual production, has obtained the good effect of operation, to improve the efficiency of power supply enterprise production, reasonable allocate generator provides data to support production schedule.This article through to analysis and research on the end of the short-term load forecasting system at home and abroad, combined with the actual situation of Da Zhou power, finally designed a set of can satisfy the actual demand of Da Zhou power short-term load forecasting system, the system realizes the real-time power load collection at the county level power supply unit, and accurately for the next period of load forecasting, load forecast data upload online first rank, so prefecture-level load forecasting data collected information can fully reflect the region’s actual load case, make the power short-term load forecasting accuracy has further improved.
