PSO based LQR‐PID output feedback for load frequency control of reduced power system model using balanced truncation

Abstract: Hydro power plants are in general more stable to the load demands and thus the change in frequency can be easily controlled. Whereas in multi-source interconnected power system the stability of the system is marginal. In certain conditions the system is also unmeasurable to implement the load frequency control. Linear Quadratic Regulator with output feedback design forms a familiar optimal choice to tackle this problem, but the technique is dependent on the choice of the weighting matrices Q and R for the perf… Show more

“…The goal of the PSO algorithm is for a large number of particles to find an optimal solution in a multidimensional superbody. The multidimensional hyperbody, which can also be referred to as the multidimensional solution space, is the search space for the particle swarm to find the optimal problem [18]. It is assumed that in solving the optimization problem, the optimal solution obtained for each optimization problem is a particle in the search space, and all the particles are extended to the D-dimensional space.…”

“…Arya reported a scaling factor-based fuzzy-PI (FPI) controller [19], fuzzy fractional-order integral derivative (FFOID) [20], and fuzzy-TIDF (FTIDN) controller [21], all tuned by the imperialist competitive algorithm (ICA) for traditional MAIPS. Pillai and Samuel [22] recently discussed designing the PSO-based LQR-PID approach for LFC using balanced truncation. In recent years, fractional-order (FO) controllers have been quite popular in control applications.…”

“…In [14][15][16][17][18], frequency restoration has been considered to control MGs. Te authors in [19][20][21][22][23][24][25][26] have employed meta-heuristic optimization-based algorithms such as the fuzzy, integration layered recurrent neural network methods, and cascade-based fractional order controllers to restore frequency deviation in multiarea systems based on hydrothermal power systems integrated with RESs.…”
