PI approach consists policy evaluation and improvement steps to determine optimal control. Optimal controller based on linear quadratic regulator (LQR) design requires complete knowledge of the system dynamics, whereas PI technique provides optimal control of system without knowing the internal dynamics. PI based optimal controller has been tested on a power system having two area deregulated. The results are used to show the effective performance of the designed controller. A comparative study has also been given in between the performance of the PI based optimal controller and LQR.<\/jats:p>","DOI":"10.3233\/jifs-169779","type":"journal-article","created":{"date-parts":[[2018,7,27]],"date-time":"2018-07-27T19:27:08Z","timestamp":1532719628000},"page":"4953-4962","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":91,"title":["AGC using adaptive optimal control approach in restructured power system"],"prefix":"10.1177","volume":"35","author":[{"given":"Akhilesh","family":"Singh","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, SEI Pithoragarh, Uttarakhand, India"}]},{"given":"Nagendra","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, IITRoorki, Uttarakhand, India"}]},{"given":"Bhagawati Prasad","family":"Joshi","sequence":"additional","affiliation":[{"name":"Department of Applied Sciences, SEI Pithoragarh, Uttarakhand, India"}]},{"given":"Kunwar Singh","family":"Vaisla","sequence":"additional","affiliation":[{"name":"Department of Computer Science, UTU, Uttarakhand, India"}]}],"member":"179","published-online":{"date-parts":[[2018,7,26]]},"reference":[{"key":"e_1_3_1_2_2","unstructured":"ElgerdO.I.
