Analysis of Fairness-promoting Optimization Schemes of Photovoltaic Curtailments for Voltage Regulation in Power Distribution Networks
arxiv(2024)
摘要
Active power curtailment of photovoltaic (PV) generation is commonly
exercised to mitigate over-voltage issues in power distribution networks.
However, fairness concerns arise as certain PV plants may experience more
significant curtailments than others depending on their locations within the
network. Existing literature tackles this issue through
fairness-promoting/aware optimization schemes. These schemes can be broadly
categorized into two types. The first type maximizes an additional fairness
objective along with the main objective of curtailment minimization. The second
type is formulated as a feedback controller, where fairness is accounted for by
assigning different weights (as feedback) in the curtailment minimization
objective for each PV plant based on previous curtailment actions. In this
work, we combine these two schemes and provide extensive analyses and
comparisons of these two fairness schemes. We compare the performance in terms
of fairness and net curtailments for several benchmark test networks.
