碩士 / 國立中山大學 / 電機工程學系研究所 / 106 / This paper investigates the control strategy of Battery Energy Storage System (BESS) to improve the system disturbance for Cimei Island caused by the photovoltaic generation system(PVGS) due to intermittent output and sudden tripping. According to the frequency response of testing on-site BESS discharge, the mathematical models with the corresponding parameters of both diesel-generators and BESS have been confirmed. The transient stability analysis of Cimei grid is executed for step increase of various levels of system loading. Finally, the relationship between the load variation and the time required for frequency drop to 59Hz is derived with regression analysis, which is embedded in the control strategy of BESS. This thesis selects the Cimei Island for case study to illustrate the effectiveness of the proposed BESS control strategy. The data of power grid such as the generators, transformers, distribution, feeder and load demand are collected. The voltage variation due to PV power generation is calculated for peak and off-peak period respectively. The transient stability analysis of Cimei power system is performed considering BESS high-speed discharge control to solve the system frequency response for variation of PV power generation and tripping of whole PV system. It is found that the implementation of BESS is very critical to maintain good transient stability and voltage quality for the offshore island power grid with high penetration of renewable energy.
