Forecasting of 10-Second Power Demand of Highly Variable Loads for Microgrid Operation Control

Abstract: This paper addresses very short-term (10 s) forecasting of power demand of highly variable loads. The main purpose of this study is to develop methods useful for this type of forecast. We have completed a comprehensive study using two different time series, which are very difficult to access in practice, of 10 s power demand characterized by big dynamics of load changes. This is an emerging and promising forecasting research topic, yet to be more widely recognized in the forecasting research community. This pr… Show more

“…RF is an ensemble method based on many single decision trees (the same type of models). In the regression task, the prediction in a single decision tree is the average target value of all instances associated with the single leaf node [41]. The final prediction is the average value of all n single decision trees.…”

“…The regularization hyperparameters depend on the algorithm used, but generally restricted are among others: the maximum depth of a single decision tree, maximum number of levels in each decision tree, minimum number of data points placed in a node before the node is split, minimum number of data points allowed in a leaf node and maximum number of nodes. The number of predictors for each of the n single decision trees is made by the random choice of k predictors from all available n predictors [41,42].…”

“…Although the scale of the offshore oil group power grid is smaller than that of the land power grid, it contains the necessary links of the land power grid such as generation-transport-transform-distribution, and is a specific offshore oil group power grid. There are many control variables in the power grid, and the system elements interact with each other, which increases the difficulty for power grid operators to dispatch the power grid [3][4]. The rapid power dispatching of offshore oil cluster power grid will make reasonable use of the control resources of the power grid, realize the power dispatching of the power grid at multiple time scales, and take into account the economy and security of the power grid operation.…”
