In the conventional two degree freedom (TDF)-internal model controller (IMC) design, obtaining suitable value of tuning parameter is much more complex and difficult. In this paper, the approach of genetic algorithm (GA) is proposed to obtain optimized value of tuning parameter used in TDF-IMC controller design. For TDF-IMC controller design, 2 nd order reduced-model is obtained using the Routh ...

The oscillation of frequency can cause the generator to run out sync in a power system. Therefore, load control (LFC) is needed reduce and prevent operation. LFC regulates governor balance turbine speed with changes existing. In this paper, proportional integral differential (PID) controller battery energy storage system (BESS) are added an improve stability parameters PID BESS optimized using ...

In this paper, the stability of load frequency control (LFC) for delayed power systems with an electric vehicle (EV) aggregator is studied based on Lyapunov theory and linear matrix inequalities (LMIs). Through mechanism analysis, LFC EV a proportional–integral–differential (PID) controller modeled. By constructing delay interval information correlation functional estimating its derivative usin...

In this paper a fuzzy logic (FL) based load frequency controller (LFC) called discrete FuzzyP+FuzzyI+FuzzyD (FP+FI+FD) is proposed to ensure the stability of a multi-source power system in restructured environment. The whale optimization algorithm (WOA) is used for optimum designing the proposed control strategy to reduce fuzzy system effort and achieve the best performance of LFC task. Further...

Abstract Modern electrical power system design will increase renewable energy sources (RES) dominance. Rotating masses, the main source of inertia in systems, have been greatly decreased producing systems. Thus, load–frequency equilibrium is an important indicator these systems' performance and safety. This work introduces a fractional‐order (FO) operator‐based cascade control structure for isl...

In the power system, any sudden load changes leads to the deviation in tie-line power and the frequency. So load frequency control is an issue in power system operation and control for supplying sufficient and reliable electric power with good quality. The main goal of the load frequency control of a power system is to maintain the frequency of each area and tie-line power flow with in prescrib...

Recently, a large number of photovoltaic (PV) power stations has been connected to power systems. Penetration of PV power stations may give some impacts on balancing between supply and demand in power systems. The representative impact is frequency variation which is caused by short-term fluctuations in power outputs from PV stations. Therefore, its investigation and evaluation are important be...

This paper provides a comparison of the performance and the design steps for four robust static output feedback Proportional-Integral-Derivative (PID) controllers. The first one presents an Iterative PID (IPID) that guarantees the stability of the closed-loop system. In the second and the third controllers, Iterative PID based on H2 (IPIDH2) and H∞ (IPIDHI) performances, respectively, are inves...
