In addition, the need of this type of solution is also highlighted by presenting the worldwide trends of thermal energy end use in buildings and peak power problems. Buildings are critical component of smart grid environments and bottom-up BEMS solutions are need of the hour to optimize the consumption and to provide consumption side flexibility. This system is able to aggregate the controls of the all-controllable resources in building to realize its flexible power capacity. This system provides a solution for consumer to aggregate the controls of \u2018behind-the-meter\u2019 small loads in short response and provide \u2018deep\u2019 demand-side flexibility. This system is capable of discovery, status check, control and management of networked loads. The main novelty of this solution is that it can handle the heterogeneity of the installed hardware system along with time bound changes in the load device network and its scalability; resulting in low maintenance requirements after deployment. The control execution latency (including data logging) of this BEMS system for an external control signal is less than one second per connected load. In addition, the system is capable of overriding the external control signal in order to maintain consumer coziness within the comfort temperature thresholds. This system provides a way forward in future for the estimation of the energy stored in the buildings in the form of heat\/temperature and use buildings as temporary batteries when electricity supply is constrained or abundant.<\/jats:p>","DOI":"10.3390\/s21030867","type":"journal-article","created":{"date-parts":[[2021,1,28]],"date-time":"2021-01-28T05:23:05Z","timestamp":1611811385000},"page":"867","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["An Automatic Aggregator of Power Flexibility in Smart Buildings Using Software Based Orchestration"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5601-0131","authenticated-orcid":false,"given":"Dharmendra","family":"Sharma","sequence":"first","affiliation":[{"name":"VTT Technical Research Centre of Finland, Kaitov\u00e4yl\u00e4 1, 90570 Oulu, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jari","family":"Rehu","sequence":"additional","affiliation":[{"name":"VTT Technical Research Centre of Finland, Kaitov\u00e4yl\u00e4 1, 90570 Oulu, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Klaus","family":"K\u00e4ns\u00e4l\u00e4","sequence":"additional","affiliation":[{"name":"VTT Technical Research Centre of Finland, Kaitov\u00e4yl\u00e4 1, 90570 Oulu, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3521-7392","authenticated-orcid":false,"given":"Heikki","family":"Ailisto","sequence":"additional","affiliation":[{"name":"VTT Technical Research Centre of Finland, Kaitov\u00e4yl\u00e4 1, 90570 Oulu, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,28]]},"reference":[{"key":"ref_1","unstructured":"(2020, August 18).
