Control and Design of Microgrids

control and design of microgrids

The work shows that the microgrid architecture is a viable solution for including distributed generation in a power system. This novel approach requires some features such as plug and play and peer to peer for each of the units in the subsystem to operate correctly.

Microgrid Communications using SDN Tech

microgrid communications

Providing ubiquitous communications connectivity that is flexible and scalable to microgrids everywhere is crucial to ensure seamless microgrid interconnection and integration with main grids and to exploit the full potential of microgrid technology. As utilities embark on the microgrid deployment journey, SDN network technologies can play an integral role to provide the everywhere connectivity they need.

Communication Infrastructures for Microgrids

communication infrastructures

Testing smart grid information and communication (ICT) infrastructures is imperative to ensure that they meet industry requirements and standards and do not compromise the grid reliability. Within the micro-grid, this requires identifying and testing ICT infrastructures for communication between distributed energy resources, building, substations, etc.

Micropower System Modeling

micropower

HOMER’s fundamental capability is simulating the long-term operation of a micropower system. Its higher-level capabilities, optimization and sensitivity analysis, rely on this simulation capability. The simulation process determines how a particular system configuration, a combination of system components of specific sizes, and an operating strategy that defines how those components work together, would behave in a given setting over a long period of time.

Microgrid Workshop Report

Microgrid workshop

Microgrids have been identified as a key component of the smart grid in order to improve system energy efficiency and reliability and to provide the possibility of grid-independence to individual end-user sites. As defined by the Microgrid Exchange Group (MEG), “A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode.”

Network Protection in Microgrids

network protection

This paper presents a novel adaptive microgrid protection concept using advanced communication system, real-time measurements and data from off-line short circuit analysis. This concept is based on an adaptation of protection relay settings with regard to a microgrid state (topology, generation and load). Further, on the hard- ware realization (basic components, communication, etc.) of this concept and numerically simulated test results are presented.

Buildings with a Smart Microgrid

Buildings and Microgrids

Buildings provide a clear and convenient target for analyzing and reducing energy use in a smart grid. Buildings are also among the dominant users of electrical energy, accounting for over 70% of total electricity use in the US in 2006 [5], [10]. This energy use is evenly split between commercial and residential buildings. The same is also true for the UCSD Smart Microgrid: most of the electricity consumption in the campus is due to buildings (thus making them the load centers). Therefore, studying the various factors that impact the energy consumption of buildings is key and can lead to mechanisms to reduce their energy use and improve the overall efficiency of a microgrid

IT Challenges for the Smart Microgrid

IT challenges microgrid

The efficiency and viability of innovative energy management applications, or the “core of the smart grid,” depends on the ability to capture fine- grained, real-time, energy-related sensor data, such as power consumption/power generation meter values, and control commands (e.g., direct load- control commands for devices which support control functions).

Cyber Security for Microgrids

Cyber Security

This document summarizes the on-going cyber security work and resulting cyber security reference architecture for a secure microgrid control system network. The architecture presented here provides guidelines and security recommendations for the implementation of a secure microgrid control system at Department of Defense (DOD) installations. The microgrid is designed using the Energy Surety MicrogridTM (ESM) methodology developed by Sandia National Laboratories (SNL).
