Frequency Support Studies of a Diesel–Wind Generation System Using Snake Optimizer-Oriented PID with UC and RFB

The present paper discusses the modeling and analysis of a diesel–wind generating system capable enough to cater electrical power requirements small consumer group or society. Due high variations load demand due changes in wind speed, frequency will be highly disturbed, hence regulate deviations turbine system, an effective controller design is necessary requirement, therefore this proposes novel based on PID scheme. parameters effectively optimized through new snake optimizer (SO) offline manner minimize isolated system. performance SO-PID for evaluated by considering integral time multiplied absolute error (ITAE), (IAE), square (ITSE). results were calculated step change load, at different instants with diverse magnitude, random patterns, they compared some recently published under similar working conditions. In addition, effect ultracapacitor (UC) redox flow battery (RFB) was investigated considered application demonstrated advantages our proposal over other studied designs.
