The document summarizes the concept of smart DC microgrids and the FREEDM approach. It discusses how smart DC microgrids can efficiently power growing digital loads directly from local renewable sources or energy storage. The FREEDM system uses solid state transformers and fault isolation devices to autonomously control microgrids even after disconnection from the main grid. It operates in different modes like transmission control, islanding, and solid state transformer islanding to maintain stability and reliably power critical loads. Distributed energy storage, fault protection using solid state devices, and hierarchical control systems are key enabling technologies of smart DC microgrids and the FREEDM approach.

Power Quality Enhancement Techniques in Hybrid AC DC Microgrid Analysis and I...
Distributed generators DGs that rely on renewable energy sources have become more important in the face of rising global temperatures. Substantial impetus will soon be supplied by wind, solar energy, biomass, mini hydro, and the use of fuel cells and microturbines. Distributed generation, where electricity is produced by a number of different renewable and unconventional energy sources, has emerged as a viable option for the construction of modern electrical systems because to its low environmental impact, scalability, and adaptability. A microgrid is a small scale electrical grid in which multiple loads and distributed generators are coordinated under a single set of controls. Microgrids are a kind of integrated energy delivery system that may either work in tandem with the main power grid or operate autonomously. The concept of a microgrid eliminates the need for several inverters in a single AC or DC grid and simplifies the connection of intermittent, renewable AC and DC power sources and loads. Equipment safety and security issues have been brought to light by the power electronic converters that link DGs to the utility grid. Greater local dependability, lower feeder losses, local voltage support, increased efficiency through waste heat use, voltage sag correction, and uninterruptible power supply are only some of the configuration options available to the client for the microgrid. In this study, we analyse the functionality of a hybrid AC DC microgrid while connected to the mains power supply. A solar array, a wind generator, and a battery are used to build a microgrid. The converters can now properly coordinate the AC and DC sub grids thanks to the added control techniques. Results were obtained by use of the MATLAB SIMULINK software environment.

Micro grid
A microgrid is a small-scale power grid that can operate independently or connect to the main grid. It allows local power generation for local loads using distributed energy resources like solar panels, batteries, and generators. Microgrids provide benefits like increased reliability, lower costs, and the ability to incorporate renewable energy. They face challenges around regulation, financing, and technology but offer a more efficient alternative to the conventional grid.

Autonomous control of interlinking converter in hybrid PV-wind microgrid
1) The document describes a control scheme for an interlinking converter in a hybrid PV-wind microgrid to autonomously share active power proportionally between its distributed generators.
2) Droop control is used to regulate the exchange of active and reactive power between the AC and DC sub-microgrids connected by the interlinking converter.
3) The control scheme uses multiple PI controllers and transforms between synchronous and rotating reference frames to produce PWM signals for the interlinking converter based on measured voltages, currents, and power values.

My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Advantages of dc micro grid
- 1. Benefits of Microgrid 1. Cost Since setting up of a grid connected sub-system is pretty costly for a remote location - it involves heavy equipment cost for setting up a sub-station including transformers - setting up a smaller Solar DC micro grid makes more financial sense. Furthermore, for a small micro grid, the transmission losses are higher for an AC system as compared to a DC system. 2. Reliability A small DC micro grid is far more reliable than a dependency on a centralized grid. This is primarily due to distributed nature of generation. With distributed sources of power, operation of one generation system is independent of the failure of another.
- 2. 3. Scalability DC microgrids are very easily scalable as compared to AC microgrids. This is primarily due to the absence of limiting equipments like transformers and relays, that are size specific and need to be replaced once, the consumer base increases. 4. Efficiency DC microgrids are comparatively more efficient due to the use of energy efficient DC appliances like BLDC motors instead of induction motors, in household appliances. They result in lower investment requirement on the generation side.
