Book Description
The purpose of this project is to investigate arc flash hazards and methods of mitigation. The definition of arc flash will be presented and, the parameters that must be determined during arc flash studies will be discussed. These parameters include incident energy levels, circuit breaker clearing times, distance to the energized equipment, and magnitude of fault current. The standards used for arc flash studies such as: National Fire Protection Association (NFPA), National Electrical Code (NEC), and related documents will also be identified and discussed. These standards are used for proper determination of workable boundary limits and Personal Protection Equipment (PPE) worn and needed for safe operation of energized electrical equipment. Addition of Distributed Generation (DG) to a system will affect some of the arc flash parameters, thus influencing the study results. These effects are greatly influenced and depend on the locations where the DG is interconnected to the system. Two scenarios will be examined, analyzed, and discussed. Commercial arc flash analysis software is used for modeling and simulation of the two arc flash studies. Study models, simulations, results and supporting conclusions derived from the commercial software will be summarized and presented. Recommendations for further mitigation and enhancement of arc flash studies will also be addressed and presented in this project.

Book Description
The integration of new sources of energy like wind power, solar-power, small-scale generation, or combined heat and power in the power grid is something that impacts a lot of stakeholders: network companies (both distribution and transmission), the owners and operators of the DG units, other end-users of the power grid (including normal consumers like you and me) and not in the least policy makers and regulators. There is a lot of misunderstanding about the impact of DG on the power grid, with one side (including mainly some but certainly not all, network companies) claiming that the lights will go out soon, whereas the other side (including some DG operators and large parks of the general public) claiming that there is nothing to worry about and that it's all a conspiracy of the large production companies that want to protect their own interests and keep the electricity price high. The authors are of the strong opinion that this is NOT the way one should approach such an important subject as the integration of new, more environmentally friendly, sources of energy in the power grid. With this book the authors aim to bring some clarity to the debate allowing all stakeholders together to move to a solution. This book will introduce systematic and transparent methods for quantifying the impact of DG on the power grid.
