An Economical Model Development For A Hybrid System Of Grid Connected Solar Pv And Electrical Storage System, Mohammad Hasan Balali

Theses and Dissertations

Energy sources management is one of the most important concern in the recent decades. There are finite amount of non-renewable energy sources and one day they will run out if they have been used as primary sources of energy. Renewable energy sources have been significantly reduced the environmental effects. For most of them the source of energy is non-depletable.

One of the concerns associated with renewable resources is uncertainty or unavailability. Energy Storage Systems (ESSs) can help to have more reliable and more efficient systems by adjusting the charge and discharge time and rate. In this study, an economic model …

Energy Neutral Operation Method For Hybrid Energy Storage Integrated With Wind Farm Using C-Rate And Frequency Spectrum Analysis, Young Jun Seo

Theses and Dissertations

In this thesis, the author describes various evaluation criteria, in particular the C-rate (charge/discharge-rate), of energy storage (ES) systems to explain the efficiency and technical benefits of battery-ultracapacitor hybrid energy storage (HES), and the technical characteristics of subsequently derived short-duration and long-duration type ES. In addition, for effective use of energy storage, a straightforward state of charge (SOC) correction method for energy neutral operation is proposed, and through a simple comparative example of ES operation, the effectiveness of HES in relation to simple ES is explained. A case is considered in which a hybrid ES controls the wind power ramp …
