Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Renewable energy test site installed at Nazarbayev University in Kazakhstan is considered as a controlled plant for modeling, design and simulation of proposed model predictive control (MPC) technique for the power system with nominal power up to 10 kW. The mathematical and simulation model of the control plant assumes that disturbance from consumer grid side is generated by pseudorandom numbers. The control strategy relies on switching between several controllers LCL-filter and is shortly discussed. The MISO control system is designed using the switching between two MPC controllers. The results of simulation show significant reduction of THD value which proves the effectiveness of the designed control.
