    摘要： A method of load forecasting for a present day includes obtaining past observed load values of at least three earlier days and identifying a relationship between the present day's load forecast and the past observed load values including unknown weights associated with the past observed load values. The values of unknown weights are determined by comparing at least one previous day's load forecast with the observed load value of the at least one previous day. The determined weight values are then used in the relationship between the present day's load forecast and the past observed load values to forecast the present day's load.

    摘要： A power generation system including an electrolyzer may be optimized taking non-linear operational constraints into account with lower processing requirements than current solutions in real time. A pre-processing module assesses non-linear operational constraints in a low-overhead manner and passes results to an optimization module. The optimization module determines an operating power value constrained in accordance with results from the pre-processing module. A post-processing module uses results from the pre-processing and optimization modules to assemble instructions to control the electrolyzer. As a result, optimization may be performed in real time.
