Modern distribution grids may suffer problems of voltage distortion, especially along radial low-voltage feeders with a high penetration intermittent, unbalanced and distorted loads generation sources. It is challenge to develop an effective voltage-regulation method using straightforward implementation. This paper proposes novel for local control balancing shunt-connected energy storage system...

Voltage-gated calcium (CaV) channels are regulated by G proteins via voltage-dependent and independent pathways. Voltage-independent regulation of calcium channels is important for intracellular calcium concentration and insulin secretion. Voltage dependence of each pathway can be elucidated by a prepulse facilitation protocol. Using this experimental approach, we compared CaV regulation by GTP...

This paper presents a new control strategy for voltage-source converters (VSCs) in the frequencyangle domain which enables dc-link voltage regulation via frequency and load angle adjustment. A major advantage of the proposed controller is emulating the behavior of synchronous machines (SMs) with proper regulation of dc-link voltage which eases integration of VSCs interfacing distributed and ren...

The regulation of the grid voltage within operational limits becomes increasingly challenging as residential photovoltaic (PV) adoption rises.

In electricity distribution networks, the increasing penetration of renewable energy generation necessitates faster and more sophisticated voltage controls. Unfortunately, recent research shows that local voltage control fails in achieving the desired regulation, unless there is some communication between the controllers. However, the communication infrastructure for distribution systems are le...

This paper proposes decentralized improved synergetic excitation controllers (ISEC) for synchronous generators to enhance transient stability and obtain satisfactory voltage regulation performance of power systems. Each generator is considered as a subsystem, for which an ISEC is designed. According to the control objectives, a manifold, which is a linear combination of the deviation of generat...
