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.

A State Space Average Model for Dynamic Microgrid Based Space Station Simulations

2017 IEEE 44th Photovoltaic Specialist Conference (PVSC), 2017
Space stations are spacecrafts designed for crew members to perform space science research and exploration for prolonged periods of time. To power a space station, solar panels are employed to absorb available sunlight, storing them in batteries for later use.

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

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 Modeling Method of Microgrid Based on Virtual Synchronous Generator

2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC), 2021
The microgrid based on the virtual synchronous generator (VSG) applies the virtual synchronous generator control strategy to provide inertia and damping to the system, but the inherent stability problems of power electronic devices cannot be avoided. The eigenvalue analysis method is a common stability research method.

Microgrid Oriented modeling of space heating system based on neural networks

Journal of Building Engineering, 2021
Abstract Balancing the energy production and consumption is a huge challenge for future smart grids . In this context, many demand-side management programs are being developed to achieve flexibility from different loads like space heating. As space heating models for flexibility simulations are an interdisciplinary field of work, complex civil ...

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 ...

An Inverter with Large Fault-tolerant Space for Battery Storage in Islanded Microgrid

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
A topology of fault-tolerant inverter with large fault-tolerant space is proposed in this paper. It can be applied to the battery storage. The inverter circuit needs to be reconstructed to keep system running normally when the power switches are faulty. The control strategy is proposed.

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 ...
