A Benchmarking Framework for Sensitivity and Comparative Analysis of Energy Harvesting Strategies via Retractable Wind Energy Harvesters
Wind power is well known for being variable. Our main insight is that one can take advantage of variability by appropriately building wind-energy harvesters that may be stowed/retracted when winds are calm. We refer to harvesters that can be deployed and retracted on command as retractable wind-energy harvesters (RWEHs). Among other advantages, stowed harvesters do not block views, do not constrain avian life, and do not make noise, and thus can increase the neighborliness of harvesting wind near or within a residential community.
RWEH control algorithms help owners to achieve the neighborliness that might be required by an RWEH hosting community while helping RWEHs' efficiency. The stowing requirements, or operation limitation agreements (OLAs), specify conditions when the retractable harvesters should be stowed (e.g., when it is not windy).
In this work, we contribute a suite of benchmarks to compare RWEH control algorithms, three families of control algorithms, and a simulator with which to run the algorithms. The benchmark suite provides workloads formed from the following workload components: 1. specifications of a harvester to be controlled, 2. a set of historical windspeeds from 30 weather stations, and 3. a variety of stowing requirements.
We derived OLAs from a survey of 304 respondents in which survey-takers were asked whether they would support RWEHs viewable from where they live and when the RWEHs should be hidden or stowed
Data Supplement for the IGSC 2019 paper ``A benchmark suite for control algorithms of retractable wind-energy harvesters''
The following files comprise the Data Supplement to which the IGSC 2019* paper ``A benchmark suite for control algorithms of retractable wind-energy harvesters'' refers:
1) Thirty training and testing files, each with approximately nine and two years, respectively, of minute-by-minute windspeeds and simulated predicted day-ahead windspeeds;
2) An eleven-year hourly electricity price
file;
3) A fuzzy-set-membership-function file describing membership in the set NOT WINDY AT for each of
the 30 weather stations;
4) A file containing sunset times for the city of St. Louis, Missouri, for all days in the years 2004-2014, inclusive, which are used in the definition of quiet hours for St. Louis;
5) A file delineating when noise is allowed for municipalities corresponding to the 30 weather stations; and
6) A document describing how the windspeed data was derived.
