This paper presents the DC voltage control design of D-STATCOM when the D-STATCOM is used for load voltage regulation. Although, the DC voltage can be controlled by active current of the D-STATCOM, reactive current still affects the DC voltage. To eliminate this effect, the control strategy with elimination effect of the reactive current is proposed and the results of the control with and witho...

Here we have examined the voltage and pH dependence of unitary Slo3 channels and used analysis of current variance to define Slo3 unitary current properties over a broader range of voltages. Despite complexity in Slo3 channel openings that precludes simple definition of the unitary conductance, average current through single Slo3 channels varies linearly with voltage at positive activation pote...

An active filter-based on-chip DC–DC voltage converter for application to distributed on-chip power supplies in multivoltage systems is described in this paper. No inductor or output capacitor is required in the proposed converter. The area of the voltage converter is therefore significantly less than that of a conventional low-dropout (LDO) regulator. Hence, the proposed circuit is appropriate...

This paper focuses on the engineering trade-offs in designing capacitor voltage balancing schemes for modular multilevel converters (MMC) HVDC: regulation performance and switching loss. MMC is driven by the on/off switch operation of numerous submodules and the key design concern is balancing submodule capacitor voltages minimizing switching transition among submodules because it represents th...

As an important form of distributed renewable energy utilization and consumption, the multi-parallel inverter microgrid system works in both isolated grid-connected operation mode. Secondary-frequency voltage-regulation control are very solving problems that appears these systems, such as secondary-frequency regulation real-time scheme, voltage reactive power balancing, under disturbances unbal...

This paper introduces a high precise direct current (DC) negative high voltage power supply. The supply’s output voltage is 25kV and its maximal output current is 100mA. The power supply uses BOOST converter for power factor correction and voltage regulation. It converts DC to high frequency (HF) alternating current (AC) square wave with phase-shifted full bridge. The voltage of the AC square w...

This paper  presents a nonlinear controller for a Distribution Static Compensator (DSTATCOM) of a microgrid incorporating the Distributed Generation (DG) units. The nonlinear control has been designed based on partial feedback linearization theory and Proportional-Integral-Derivative (PID) controllers try to adjust the voltage and trace the output. This paper has proposed a combination of a fuz...

With the intensive integration of photovoltaic (PV) sources into low-voltage distribution networks (LVDN), nodal voltage limit violations and fluctuation problem cause concerns on safety operation a power system. The intermittent, stochastic, fluctuating characteristics PV output leads to frequent fast voltages. To address violation problem, this paper proposes distributed regulation method bas...

The emergence of distributed generation such as solar systems has introduced new challenges in distribution networks that are becoming more apparent with increasing penetration levels. time mismatch between peak load and can make voltage levels swing towards extreme limits during a day. Distribution network service providers struggling to cater for installations while ensuring the quality stead...
