Analysis of Flexibility Requirement against the Variability of Renewable Energy in Power Systems
Abstract
The share of wind and solar power has been growing very rapidly in many countries due to renewable energy dissemination policies and falling technology costs. However, as the share of renewable energy is increasing, the intermittent characteristic of renewable energy is increasing, making it difficult to maintain the balance of power supply and demand. The operator of the power system must control the variation in renewable energy generation through the operation of the power supply facilities for balance of power system. Frequent power fluctuations due to an increased share of renewable energy can put a lot of pressure on the power system, and the flexibility of existing supply facilities in the power system alone may not control the variation in renewable energy. If there is a situation in which the existing supply facilities in the power system cannot cope with fluctuations in renewable energy due to lack of flexible resources, the power system operator often resort to curtailment of renewable energy. However curtailment reduces the capacity factor of solar and wind power and thus negatively affect both their economic attractiveness and system benefits. From this perspective, this thesis analyzes flexibility requirements in power systems based on the analysis of characteristics of short-cycle and long-cycle variation of net load through discrete Fourier transformations.
