In the new millennium, traditional electrical power systems have undergone a significant change driven by set of requirements arising from evolving and changing technology. Thus, fundamental changes occurred in way energy is produced, transmitted, distributed. This situation has revealed need to expand existing networks or establish networks. The available literature that particular attention l...

Although solar photovoltaics (PV) are recognized as a promising source of clean energy production, researchers and policy makers need to know the optimum level of solar PV capacity penetration into the existing generation structure under the current fuel mix for the region. As the level of installed PV capacity increases, it is possible that the aggregated generation mix could produce electrica...

ii Acknowledgments The authors wish to acknowledge the extensive contributions of the following people to this report. iii Preface Now is the time to begin planning for the integration of significant quantities of distributed renewable energy onto the electricity grid. Factors such as growing concern about climate change, adoption of state-level renewable portfolio standards and incentives, and...

Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...

The past decade has seen advancements in renewable energy technology, making even smaller solar and wind installations at residential level an economically viable option. Hence, large amounts of distributed energy sources (DERs) with high penetration of renewables will form a key component of an urban energy grid. This not only reduces the inertia of the system but also injects large unpredicta...

With the increasing penetration of renewable energy in power systems, fluctuation of renewable energy power plants has great influence on stability of the system, and renewable power curtailment is also becoming more and more serious due to the insufficient consumptive ability of local power grid. In order to maximize the utilization of renewable energy, this paper focuses on the generation sch...
