The paper focuses on reliability assessment of power systems with wind power generation. A Monte Carlo based production cost simulation model is introduced in the paper. The model closely simulates actual system operation processes and takes system random behaviors into account. A simplified unit commitment method is created to fit the simulation for reliability evaluation purpose. The effects of...
The Puerto Rico Electric Power Authority (PREPA) supports an orderly development of the renewable energy potential on the islands. To attain this goal, PREPA is conducting science-based analytical studies and research to increase knowledge on these technologies. As part of this effort, PREPA commissioned the Electric Power Research Institute (EPRI) to assess the potential impacts that different penetration...
The combination of offshore wind generation with international transmission cables is a highly discussed topic in Europe, especially for the North Sea and the Baltic Sea. The offshore wind park location Kriegers Flak in the Baltic Sea could combine offshore wind generation in the Swedish, German and Danish zones, and several design options with regard to cabling are under discussion. Choosing a certain...
As power systems evolve to incorporate greater penetrations of variable renewables, the demand for flexibility within the system is increased. Combined Cycle Gas Turbines (CCGTs) are traditionally considered as inflexible units but those which incorporate a steam bypass stack are capable of open-cycle operation. Facilitating these units to operate in open-cycle mode is shown to improve system reliability...
