Power System Grid Planning with Distributed Generation
Distributed Generation (DG) is one of the technologies approved by the South African government for the country's generation expansion to meet future load demand and to support economic growth. DGs change the conventional power flow (generation, transmission to distribution) by injecting real and …

Energy management system of a microgrid with distributed generation
… required to control the flow of power and match generation with the load within a microgrid during grid-connected and islanded modes of operation. In grid-connected mode, a microgrid draws/supplies power from/to the main grid, depending on the generation and load requirements, and with suitable …

Distributed Generation: Issues Concerning a Changing Power Grid Paradigm
Distributed generation is becoming increasingly prevalent on power grids around the world. Conventional designs and grid operations are not always sufficient for handling the implementation of distributed generation units; the new generation may result in undesirable operating conditions, or system …

Architectures and Algorithms for Distributed Generation Control of Microgrids
… new control paradigms, e.g., those that rely on distributed computations rather than a centralized processor. We address the problem of distributed generation control in islanded ac microgrids with and without inertia. In the case of microgrids comprising heterogeneous generators, some of which …

Metering and adaptive protection for a microgrid with distributed generation
The main objective of this project is to develop an adaptive relaying system that will protect the microgrid both in connected and isolated modes. Therefore the settings for the different relays will be observed for the two modes of operation. This will determine whether they are correctly …
