Abstract
In Poland, the expansion of the introduction of wind power generation has been recently accelerating as a global warming countermeasure mainly in the area of northern Poland along the Baltic Sea. The transmission company (PSE-Operator, “PSE”) and the distribution company in the northern area (ENERGA-Operator, “ENERGA”) have faced an urgent issue of reinforcement in transmission lines to tackle with such expansion. Moreover, concerns have been increasing about negative impacts on the supply-demand balance and the power quality due to fluctuations in wind power generation output.
We have analyzed and examined power system stabilization measures such as special protection scheme (SPS) with a minimum cost for expanding the introduction volume of wind power generation in order to address such concerns. In addition, we have examined measures for stable operation of the power system through the application of smart grid technologies such as storage batteries for the power system, and studied the possible commercialization of such measures.
Through the analysis we confirmed the effect of introduction of SPS or decision support system for operators which conduct a control of the power system such as generation shedding against overload which could be caused in the event of N-1 fault when the introduction volume of wind power generation is expanded. And we also confirmed the effect of introduction of storage batteries that suppress extra area flow fluctuations of wind power generation and shave a peak of demand.
