Abstract: In the operation of a microgrid, forecasting of load is an important task. A microgrid, is an integrated energy system comprises price-sensitive loads, energy storage and Distributed Energy Resources (DERs) which could supply power and heat. To operate such an integrated system, Microgrid Energy Management System (MG-EMS) is required to monitor and control these devices. Load forecasting which predicts the total customer load in a district plays an important role in the MG-EMS. Some MG-EMS's functions such as economic dispatch require load forecast with shorter forecast lead time, from a single minute to several dozen minutes and this is referred to as very short-term load forecasting (VSTLF). VSTLF has a significant impact on the efficient market operation, controlling and planning of microgrids. The accuracy of the forecast greatly depends on the algorithms used in prediction. Load forecasting algorithms which give accurate forecast values will result in economic savings as well as enhancing security of the system operation. With the 24-hour ahead load forecast values, Unit Commitment which determines the half-hourly (or quarter-hourly) on/off schedules of DERs and their power generation for the next 24 hours can be executed.
