Dependency on thermal generation and continued wind power growth in Europe due to renewable energy and greenhouse gas emissions targets has resulted in an interesting set of challenges for power systems. The variability of wind power impacts dispatch and balancing by grid operators, power plant operations by generating companies and market wholesale costs. This paper quantifies the effects of high...
In many power systems, fluctuating in-feed contributes a big share of total energy produced. This means new challenges to operate the system securely. In this paper, a risk-based method for security assessment of power systems is presented. The method takes the probability and severity of contingencies into account. The method proposed considers also the forecast errors of fluctuating in-feed and...
The impact of wind power generation on the reserve levels has been studied in this paper through the simulation of a one-year daily unit commitment schedule for a benchmark power system. The case study shows that under the hybrid “N-1” plus “ 3σ ” security criterion, there exists a complex relationship among reserve levels, wind penetration and the relative size the conventional units. When such units...
