Voltage Restoration and Adjustable Current Sharing for DC Microgrid With Time Delay via Distributed Secondary Control

IEEE Transactions on Sustainable Energy, 2021
As a key part of modern power systems, DC microgrid is becoming increasingly important. Among different control methods for DC microgrid, secondary control has been widely investigated since it can guarantee both current sharing and DC bus voltage ...

Secondary Control in AC Microgrids - Challenges and Solutions

Proceedings of the 4th International Conference on Smart Cities and Green ICT Systems, 2015
The hierarchical control structure of a microgrid can be described as consisting of four levels: processing, sensing and adjusting, monitoring and supervising, and maintenance and optimizing. This paper focuses on the secondary control level, which can be classified as centralized or decentralized control.

Memory-Based Event-Triggered Control for Distributed Secondary Control in DC Microgrids With Quantized Communication

IEEE transactions on industrial electronics (1982. Print)
This article investigates the distributed secondary control of a dc microgrid, where the distributed generation units (DGUs) are connected through limited communication.

Distributed Event-Triggered Secondary Control for Islanded Microgrids With Proper Trigger Condition Checking Period

IEEE Transactions on Smart Grid, 2021
The conventional distributed secondary control of islanded microgrids (MGs) often requires each distributed generator (DG) to communicate with its neighboring DGs successively with a small fixed sampling period, which is neither economical nor efficient ...

CONTROL OF SECRETION OF PARATHYROID HORMONE IN SECONDARY HYPERPARATHYROIDISM

Clinical Endocrinology, 1982
The response of the parathyroids to an infusion of calcium has been studied in patients with secondary hyperparathyroidism due to either vitamin D deficiency or to chronic renal failure. Two specific homologous immunoradiometric assays for human parathyroid hormone (PTH) have been used to assess the response, one specific for the amino‐terminus (N‐PTH),

Distributed Learning-Based Secondary Control for Islanded DC Microgrids: A High-Order Fully Actuated System Approach

IEEE transactions on industrial electronics (1982. Print)
In this article, a converter-based multibus dc microgrid (MG) in series is studied, in which the tradeoff between voltage recovery and current equalization has been a hot topic of interest.

Accurate Distributed Secondary Control for DC Microgrids Considering Communication Delays: A Surplus Consensus-Based Approach

IEEE Transactions on Smart Grid, 2022
The state-of-the-art dynamic consensus-based microgrid (MG) secondary controls suffer from the communication delay effect. Specifically, the system could not converge to the desired operating points with time-delayed communications.

Control of Secondary Pests, 1988

Insecticide and Acaricide Tests, 1989
Abstract Cotton was planted 15 Apr at the Texas Agricultural Experiment Station annex farm in Mercedes. The experimental design was a randomized complete block with 5 replicates. Plots were 2 beds wide and 40 ft long with 2 beds of sorghum between plots and 20-ft alleys between plots in rows. Applications were made with a tractor-mounted
