iludrt I

Overall asssssmenl:

Rapidly inqeasing _share of renewable (uncontrollable) energry sources motivates research in the area of modering and rear-time optimization of energy (smart) grids, microgrids, and its components, thus motivating _this work.

The author demonstrates good underslanding _{of the} topic including both mode ing and optimization parts, which is evidenl from the theoretical part and high number of cited literature.

The main benefit of the work is the proposed Economic Model predidive controller that performs real-time optimization

ofa

sm€rt microgrid. verification _of the optimalcontrol strategy is ierformed ^via simulations _{in Matlab} simulink. The controller provides optimal regimes for

controll;|le

components and reduses _the operalional cost of the microgrid.

oespite good overall assessment, some parts

oflhe

work are sligh y unclear and require more delailed explanation. _E.g. praciical reasoning _for the micrtogrid structure, infl;ence _of simplifying assumptions on the model accuracy (miqogrid _model verification), and/or comparison of the investmeni _{cosrs to} the achieved _savings.

Questions for the dofonse:

l

^Vvhat could be another potential _source of increasing the savings without signiticant investments in residenlial domain that could be included _into the optimization _Drobtem?

Wlat

will/can happen to the consumption profile if the real-time eleclricity pricing is introduced _in the grid? _{How it} will influence the @nsumption prediciive _model?

@erall dasslMion:

work meets the Masler degree requirements _and thgrefore r re@mmend _{it for} defense I

suggest to classifo this work by grade Excellent minus (1,
