An accurate method with acceptable training time using load and meteorological data. Load forecasting in power microgrids and load management systems is still a challenge and needs an accurate method. Although in recent years, short-term load forecasting is done by statistical or learning algorithms.
By contrast, a stochastic model for microgrid load forecasting is proposed in, but the load features are not taken into account in the constructed model. Therefore, due to its smaller capacity, higher volatility, and higher randomness, the microgrid load is more challenging to forecast than in a large power grid.
However, deterministic load forecasting cannot reveal the load pattern and uncertainty of controllable load in a microgrid, where the prediction errors may exceed the expected range due to the high volatility and strong randomness.
