Power system state estimation is used to ensure the stableness of the grid and prevent blackouts. A real time power quality assessment is much needed for power systems in which power disturbances like harmonics, swell and sag can affect the performance.
Among the data mining methods the most widely used are: Short-term load forecasting based on artificial neural network was proposed by Zhang et al. Maryamah, Moh. Hence it ensures solution to the problemslike optimal state estimation and optimal power flow. They incur significant cost loading the data on each step and writing it back to replicated storage.
Multiple Linear Regression was used by Hong. Instead, they rebuild lost data on failure using lineage: Spark also supports a pseudo-distributed local mode, usually used only for development or testing purposes, where distributed storage is not required and the local file system can be used instead; in such a scenario, Spark is run on a single machine with one executor per CPU core.
It ingests data in mini-batches and performs RDD transformations on those mini-batches of data.
