6 FAQs about [Microgrid voltage regulation]
What are the control objectives of DC microgrids?
In the present paper, we focus on two main control objectives in the operation of DC microgrids, namely voltage regulation and load sharing. Voltage regulation seeks to maintain the bus voltages within a reasonable neighborhood around their rated values. Load sharing means to ensure a fair power allocation amongst DGs.
Do microgrids need voltage regulation?
If the microgrid is large enough, voltage regulation may be required in order to avoid the nuisance of voltage relays tripping and cascade events. In Table 7 a set of candidate control strategies for the voltage control is summarized.
What is a dc microgrid voltage stabilization control strategy?
A DC microgrid voltage stabilization control strategy is designed based on droop control and improved PI control, which effectively improves the stability of DC microgrid operation. The simulation model of a DC microgrid system with composite energy storage is built on a simulation platform.
Are current sharing and voltage regulation important in Multi-Bus DC microgrids?
It is well known that accurate current sharing and voltage regulation are both important, yet conflicting control objectives in multi-bus DC microgrids. In this paper a distributed control scheme is proposed, which simultaneously considers these two control objectives via a trade-off factor.
What is microgrid control?
Microgrids’ control purposes are to maintain stable system operation, regulate low voltage, and equalize load sharing among distributed generators per unit under steady-state conditions (DGs). Local control is a good energy management technique in a hybrid microgrid.
What are the three voltage control strategies for DC microgrids?
In this paper, the performances of three voltage control strategies for DC microgrids are compared, including the proportion integration (PI) control, the fuzzy PI control and particle swarm optimization (PSO) PI control.
