This paper introduces a novel Bi-directional DC-DC converter with artificial neural network controller (ANN).Bidirectional power flow is obtained by the same power components and provides a simple, efficient, and galvanically isolated converter. In the presence of DC mains the converter operates as buck converter and charges the battery. When the DC main fails, the converter operates as boost c...

OBJECTIVE Femoral arterial cannulation is associated with a significant risk of lower limb ischemia. The aim of the study was to assess the pressure and flow in the femoral artery using a novel bidirectional femoral cannula in a sheep model of peripheral cardiopulmonary bypass. METHODS Peripheral cardiopulmonary bypass was established using a multistage venous cannula inserted into the intern...

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...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

Distribution smart grid is very important part of the smart grid. Utilities use Distribution Management System (DMS) as supervisory control layer at the power system control centers. State Estimation (SE) and Volt-Var Control (VVC) are the prime applications of the DMS. In the modern DMS, SE is required for extensive monitoring and control of the entire distribution network. In the presence of ...
