Probabilistic Sizing of Islanded Microgrid Considering Temperature Effect on PV Array

Abstract

The energy efficient microgrid (MG) plays a vital role in electrifying the remote community. But the over/under sized MG resulted in high-cost or unreliable electricity. So, the optimal sizing of MG is implemented in this paper by identifying the optimal control strategy for the highly reliable solar PV/Battery/Diesel generator-based configuration. The negative impact of temperature on the performance of PV array is included in optimal sizing and the resulted changes in the capacity of MG components are estimated and presented. Also, the uncertainty of the design parameters is included in optimal sizing through the probabilistic approach and the distribution of optimal sizes for each MG components are presented to identify the size which provides highest reliability for sensitive applications. It is proved that additional 11% PV array capacity is required to compensate the power loss due to temperature effect but with the advantage of reduction in battery and converter size.

Probabilistic Techno-Economic Design of Isolated Microgrid

“…The randomness of the hourly values is not included, instead, the average of the hourly values is considered for the design parameters. The negative effect of the temperature rise of PV panel on its electricity generation, which results in the power loss of up to 60% [32] and hence affect its power generation capacity [33], is also not included in the optimal design of the MG. Similarly, the techno-economic optimization of the PV/Battery/DG based islanded MG reported in [34] considered the intra hour variability of the solar power and load.…”
