renewable energy sources (res), especially wind power plants, have high priority of promotion in the energy policies worldwide. an increasing share of res and distributed generation (dg), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. paper presented here concentrates on electricity storage systems technologies and applications pinpoint...

This research conducts a technical and economic feasibility study of multi-energy hybrid systems (MEHS) combining different renewables for northern climate city Finland to address issues replacing fossil energy by renewable sources (RES) achieve zero carbon emissions. The MEHS include geothermal, biomass solar energy. selected city-study site is the Olympic Training Center occupied heterogeneou...

In this paper, we introduce a new class of Lyapunov functionals for analyzing hybrid dynamical systems. This class can be thought of as a generalization of the Lyapunov functional introduced by Yakubovich for systems with hysteresis nonlinearities which incorporates path integrals that account for the energy loss or gain every time a hysteresis loop is traversed. Hence, these Lyapunov functiona...

Hybrid power system can be used to reduce energy storage requirements. The influence of the Deficiency of Power Supply Probability (DPSP), Relative Excess Power Generated (REPG), Energy to Load Ratio (ELR), fraction of PV and wind energy, and coverage of PV and wind energy against the system size and performance were analyzed. The technical feasibility of PV-wind hybrid system in given range of...

This paper presents a comprehensive review of machine learning (ML) based approaches, especially artificial neural networks (ANNs) in time series data prediction problems. According to literature, around 80% the world’s total energy demand is supplied either through fuel-based sources such as oil, gas, and coal or nuclear-based sources. Literature also shows that shortage fossil fuels inevitabl...

Received Feb 3, 2017 Revised Mar 18, 2017 Accepted May 5, 2017 Dual input dc-dc converters have two input voltage sources or one input source and an energy storage system like ultra capacitor, PV, battery, super capacitors and a single output load. In order to process the power in hybrid energy systems using reduced part count, researchers have proposed several multi-input dc-dc power converter...
