State space modeling and stability assessment for a microgrid

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
The concept of microgrid can integrate large amounts of Distributed Generations (DG) into power system and provide higher reliability, energy security and surety to critical loads. A Virtual Droop Control (VDC) method is proposed for the power management and voltage and frequency regulation and has been applied to the Fort Sill microgrid.

State-Space Modeling and Reachability Analysis for a DC Microgrid

2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019
In a DC microgrid containing parallel voltage sources, distributed control algorithms such as droop control methods are mainly employed. These controllers depend on the nominal bus voltage and the droop coefficients to operate properly. In the DC microgrid with PV arrays there are uncertainties in the PV current.

State space modelling, analysis and optimization of microgrid droop controller

2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA), 2017
The concept of microgrid has become more relevant due to the increase in the use of distributed energy resources. However, the important factors which are to be considered are their ability to control the power flow and stability of the system. Droop control strategy requires no communication system and realizes the “plug and play” function between ...

Design of Space Microgrid for Manned Lunar Base:Spinning-in Terrestrial Technologies

2019 European Space Power Conference (ESPC), 2019
The present study analyses the design of the power system of a manned lunar base, in Shackleton crater, using well-established terrestrial technologies deriving from DC microgrids with increased fault-Tolerance needs. Expected luminance data from 2020 is used in order to select the ideal base location in terms of mean annual solar Irradiance, according

A State-Space Modeling Framework for Microgrid Small-Signal Stability Analysis

2018 Power Systems Computation Conference (PSCC), 2018
A state-space modeling framework for microgrid small-signal stability analysis is developed in this paper. The proposed framework is intrinsically modular, in the sense that each elementary microgrid component is individually modeled and then aggregated into a single model for the entire microgrid.

Improved state-space model and analysis of islanding inverter-based microgrid

2013 IEEE International Symposium on Industrial Electronics, 2013
Based on the traditional modeling method of the inverter-based microgrid, this paper makes some improvement on the state-space model to describe the microgrid more precisely. The coupling item, variation of common rotating angle, in the state-matrix of inverters model introduced by the common rotating reference frame are considered, which isn't ...

A First Resilient DC-Dominated Microgrid for Mission-Critical Space Applications

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2016
The advanced electrical power system (AEPS) is the first remote, resilient dc microgrid for mission-critical space applications. This structured microgrid features resiliency, energy balancing, autonomy, standard interface, fault tolerance, fault isolation, modularity, and scalability. The basic standard building modules are first described.

Location of Fault in a DC Microgrid using State Space Model Based Approach

2020 IEEE International Conference on Power Electronics, Smart Grid and Renewable Energy (PESGRE2020), 2020
In DC microgrids (DCMG), the fast detection of accurate location of fault accelerates maintenance, supply restoration process, and decreases the duration of power outage. Protection system design is complicated for a DC microgrid with ring configuration due to bidirectional power flow.

State-Space Modeling, Analysis, and Distributed Secondary Frequency Control of Isolated Microgrids

IEEE Transactions on Energy Conversion, 2018
A comprehensive modular state-space model of a microgrid is developed that handles basic components and loads, as well as inverter-based generation, such as PQ inverter and voltage-source inverter (VSI). Specifically, the developed model is suitable for control design utilizing the nominal set-point values of frequency and voltage of the VSI inverters,
