This paper discusses the control of flexible microgrids, consisting of a Redox Flow Batteries (RFB) and a new power conditioning system (PCS) for the RFB. Considering the importance of energy storage, this study is essential in power systems that are developed cautiously. RFB is connected to power system by a DC/DC or DC/AC converter to produce a DC voltage. It is very important that this conve...

High Tc superconducting (HTS) cables and their application to develop a DC power transmission system with substantial advantages have been studied. Technical analysis of the HTS DC electrical power transmission system behaviours have been carried out with the HTS DC cable technology employed and the system models built. Index Terms -High Temperature Superconductor (HTS), HTS Cable, DC Transmiss...

Conventionally Grid Connected Solar PV plants initially generates DC power and then converted to AC via inverters and connected into AC grid for power transmission. Depending on the size of the plant, required environmental condition and land availability large PV plants are generally located far away from the load centre. Hence reduction of transmission loss and incised transmission capacity e...

Because the power systemload the randomness of the nature, power transmission of AC induction system has the low efficiency. In order to improve the transmission efficiency,the transmission efficiency influenced factors of the system is analyzed. Based on the current source power transfer system, DC/DC circuit for dynamic adjustment method is proposed. The method ensures that the transmission e...

High power and high voltage gain DC-DC converters are key to high-voltage DC (HVDC) power transmission for offshore wind power. This paper presents an isolated ultra-high step-up DC-DC converter in matrix transformer configuration. A flyback-forward converter is adopted as the power cell and the secondary side matrix connection is introduced to increase the power level and to improve fault tole...

This paper is concerned with transient dynamics and stability of an electric power system with dc transmission. Nowadays dc transmission systems are widely applied to conventional electric power systems. However, transient dynamics of ac/dc power systems, affected by active power which flows into dc transmissions, is not entirely understood. In this paper an unsymmetrical swing equation system ...
