DC Voltage Control and Power-Sharing of Multi-Terminal DC Grids Based on Optimal DC Power Flow and Flexible Voltage Droop Strategy
This paper develops an effective control framework for DC voltage control and power-sharing of multi-terminal DC (MTDC) grids based on an optimal power flow (OPF) procedure and the voltage-droop control. In the proposed approach, an OPF algorithm is executed at the secondary level to find optimal reference of DC voltages and active powers of all voltage-regulating converters. Then, the voltage ...
متن کاملControl Strategies for Smart Low Voltage Grids – the Project Dg Demonet – Smart Lv Grid
Upcoming challenges for LV grids include a high penetration of distributed energy resources and electric vehicles. The project “DG DemoNet – Smart LV Grid” aims to enable an efficient and cost effective use of existing grid infrastructures based on a three-step concept: intelligent planning, on-line monitoring and active LV grid management. Communication-based systems for automatic control conc...
متن کاملCost-effective Communication and Control Architectures for Active Low Voltage Grids
The monitoring and control of low voltage distribution grids has historically been disregarded due to the unidirectional flow of power. However, nowadays the electric power system is being modernized to enable a sustainable energy system. This is assisted by the smart grids concept, which incorporates the new types of loads, the active energy consumers, often called 'prosumers', and the higher ...
متن کاملAn Advanced Hysteresis Controller to Improve Voltage Profile of Power System with PV Units: A Smart Grid Power Exchange Framework
Unlike traditional power grids, smart grids have the advantage of bidirectional power flow and having distributed generations. Distributed generation systems are usually supplied by renewable sources which can cause unpredicted voltage fluctuations as a result of being intermittent. While traditional compensating devices deal with the problem of voltage fluctuation and reduced power quality wit...
متن کاملLow-Voltage Consumption Coordination for Loss Minimization and Voltage Control
This work presents a strategy for minimizing active power losses in low-voltage grids, by coordinating the consumption of electric vehicles and power generation from solar panels. We show that minimizing losses, also reduces voltage variations, and illustrate how this may be employed for increasing the number of electric vehicles and photovoltaic systems in the grid without violating grid const...
