Evaluation of geographical aggregation of solar photovoltaic generation in Singapore

The capacity of photovoltaic generation in Singapore is rapidly increasing. Large and rapid changes in the output of PV plants are possible because of the intermittent and stochastic nature of solar PV. Such uncertain power fluctuations may cause many issues that threaten the secure and reliable...

description The capacity of photovoltaic generation in Singapore is rapidly increasing.

This dissertation put forward several parameters which are used to evaluate the smoothing effect of the geographical distribution of the PV plants. Also some figures in the time and frequency domain is proposed. After the data analysis processing, the results of the different timescale and combination were compared. So at last the influence factor of the smoothing effect is given and discussed based on the result figures.
