Distribution grid

Accurate forecasting of the electrical load is a critical element for grid operators to make well-informed decisions concerning electricity generation, transmission, and distribution. In this study, an Extreme Learning Machine (ELM) model was proposed and compared with four other machine learning models including Artificial Neural Networks (ANN), Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU).

This paper presents the results and assessment of the groundwater exploitation reserves in coastal areas of Ninh Thuan province. The research was based on determining the exploitation reserves of all grid cells with dimensions 500 m × 500 m distributed in fresh-salted water areas of the Holocene (qh) and Pleistocene (qp) aquifers. Each grid was assigned the corrected hydrogeological parameter values (depth, gravity coefficient, hydraulic conductivity, and drawdown level).

This article introduces a method which could quickly delineate short-circuit fault location by establishing the corresponding matrix between nodes on grid and short circuit current value. A 22kV Daklak distribution grid – E471 line is studied. A big data of input as load, source, season coefficient, utilization coefficient and all four types of short circuit have been considered and calculated in detail.

Grid-connected photovoltaic power systems are power systems energised by photovoltaic panels which are connected to the utility grid. Grid-connected photovoltaic power systems comprise of Photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connection equipments. Unlike Stand-alone photovoltaic power systems these systems do not have batteries. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.[1]...
