Zhrnutie	Droop Control is a decentralized control method that enables independent generators (inverters, microgrids) to operate synchronously without direct communication. Introduced by Guerrero et al. in 2013 for microgrids, droop control uses frequency and voltage deviations as signals to share power. By making generator output depend on frequency and voltage (like synchronous generators), microgrids achieve plug-and-play operation. Essential for modern distributed energy resources and grid resilience.	A Phase-Locked Loop (PLL) is a feedback control system that synchronizes an output oscillator to match the phase and frequency of an input signal. Introduced by Gardner in 1966, PLLs are ubiquitous in communications, radar, clock distribution, and power systems. The PLL continuously adjusts its oscillator frequency to minimize the phase error with the input, achieving lock. PLLs are fundamental to modern electronic systems.	Unit Commitment (UC) is the problem of deciding which power generation units should be switched on or off over a planning horizon (typically 24-168 hours) to minimize total operating cost while meeting demand and reserve requirements. Introduced by Baldwin et al. in 1959, UC is a fundamental scheduling problem in power system operations, combining combinatorial optimization (which units to commit) with continuous optimization (optimal power output). UC remains one of the most important and computationally challenging problems in power systems.
