Abstract Rock bolts are tendons or cables that commonly used in mining engineering and civil to reinforce excavated rock masses soils.

The main objective of this study was to conduct multi-stage and multi-variant prognostic research assess the impact e-mobility development on Polish power system for period 2022–2027. steps were as follows: forecast number electric vehicles (using seven methods), annual demand arising solely out operation vehicles, with without growth six daily profiles typical days three methods). For purpose ...

The presence of an electrical de-regulated market reinforces the need of forecast. Actions like network management, load dispatch and network reconfiguration under quality of service constraints, require reliable load forecasts. This paper establishes a methodological approach based on a Gaussian Process Model in order to choose an efficient endogenous information to be included in the input ve...

Transformation in the South African power sector and new load patterns necessitated a review of models used for financial, technical tariff analysis. This pilot study took advantage available data customer measurements on medium Voltage (MV) feeders Eskom's database. Load with distinct profiles typical days were developed non-overlapping classes using set coherent parameters derived from MV chr...

Over the past decades, power companies have been implementing load forecasting to determine trends in electric system (EPS); therefore, is applied solve problems of management and development systems. This paper considers issue building a model medium-term graphs for EPS with specific properties, based on use ensemble machine learning methods. implements approach identification most significant...
