Models for HLI analysis of power system with offshore wind farms and distributed generation

This paper focuses on reliability assessment of power systems with large wind installations. Due to the variability of the wind and the availability of components, reliability of wind farms is relevant both to its design and to investigate its influence on the energy balance of the whole system. Furthermore, a power system must keep a high level of reliability in order to meet the demand satisfactorily. A model for generation adequacy analysis is therefore presented, including components such as conventional power plants, distributed generation and offshore wind farms. Particular attention is paid to the latter aspect, since many factors affect it. The assessment is performed by a sequential Monte Carlo simulation, and results for different power systems are presented in the form of indices and probability distributions. These results can be used for preliminary assessment of power system reliability and as reference for more detailed analyses with the inclusion of transmission facilities. Index Terms Monte Carlo methods, power generation reliability, power system simulation, wind power generation.
