In this research, a modified Osprey optimization algorithm (MOOA) is presented to optimize droop control parameters. MOOA is a modification of the Osprey optimization algorithm by adding levy flight which has the advantage of exploiting a wider space and being adaptive to environmental changes. This research also modifies droop control, Proportional Integral Derivative (PID) is applied to secondary control. PID has flexibility in responding to changes in system conditions and fast response in dealing with system changes. The PID parameters are optimized using MOOA and are called MOOA-PID. The MOOA method is validated using 23 CEC2017 benchmarks-function and performance on DC microgrid systems. This research uses the latest algorithms as a comparison, namely One-to-One Based Optimizer (OOBO), Preschool Educational Optimization Algorithm (PEOA), and the red-tailed hawk (RTH) algorithm in testing 23 CEC2017 benchmark functions. From the simulation of the 23 CEC2017 benchmark function, it is known that the MOOA method has better capabilities. MOOA has advantages in 15 out of 23 benchmark functions. In DC microgrid system testing, MOOAPID is compared with the Proportional Integral (PI) method which is optimized with MOOA and is called MOOA-PI. Testing on the microgrid is aimed at determining the performance of the transient response of power, voltage and current in the system. Tests on DC microgrid systems found that the application of MOOA-PID in secondary control had better capabilities than MOOA-PI. The average value of voltage overshoot from MOOA-PID is 9.828% better than MOOA-PI. The average ITSE MOOA-PID score is 22.3% better than MOOA-PI. [ABSTRACT FROM AUTHOR]

This paper described a hybrid system that combines micro hydro, wind turbines and fuel cells for remote and isolated areas. The system uses Fuzzy Logic Controllers for tracking the maximum power of wind generator and balancing the power demand using fuel cell. The proposed system provides voltage and frequency as satisfactory as grid quality. The maximum power tracker applied Fuzzy Logic with 3 inputs, e.g. the rotor speed, error and Δ error of rotor speed. The outputs of Fuzzy Logic are the id and iq for adjusting the generator speed control. The balancing of power is met by the electrolysis, which is controlled by dc-to-dc converter. The dc converter is driven by Fuzzy Logic. The simulation results indicate the proposed control system stabilizes the voltage at constantly 220 volt and frequency 49.8 to 50.5 Hz. under various load changes. The best maximum power tracked is 96.2 % when the wind speed is 10 m/s. [ABSTRACT FROM AUTHOR]
