Electric load forecasting is an important issue for a power utility, associated with the management of daily operations such as energy transfer scheduling, unit commitment, and load dispatch. Inspired by strong non-linear learning capability of support vector regression (SVR), this paper presents a SVR model hybridized with the empirical mode decomposition (EMD) method and auto regression (AR) ...

Hajime Urai, Dr. Eng. Takahide Matsuo Hiroaki Hashimoto Tatsuro Kato, Dr. Eng. OVERVIEW: The market for electric power transmission systems is expected to grow strongly, driven by growing demand for electric power in emerging economies and the adoption of renewable energy. Transformers, circuit breakers, and switchgear are important components of these electric power transmission systems. The e...

The electric power load forecasting is critical for stable electric power system supply. In this paper, a seasonal ARIMA model was used to effectively forecast power load data characterized using periodicity. A numerical example reveals that the seasonal ARIMA model effectively forecast periodic power load.

In order to solve the problems of high energy consumption and serious waste heat in traditional oil cooler Marine hydraulic system, recovery reuse temperature control system is proposed. The test platform has been established, influence electrical load, flow rate working medium on operation characteristics studied. experimental results show that under same condition, compared with specification...

The genetic algorithm (GA) based solution techniques are found suitable for optimization because of their ability of simultaneous multidimensional search. Many GA-variants have been tried in the past to solve optimal power flow (OPF), one of the nonlinear problems of electric power system. The issues like convergence speed and accuracy of the optimal solution obtained after number of generation...

objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...
