Abstract
This paper proposed an improved structure of Proportional Integral Derivative (PID) controller called as Integral Proportional Derivative (I-PD), applied for Automatic Generation Control (AGC) of Multi-Source Interconnected Power System (IPS). The parameters of the proposed controller are optimized with a newly developed, powerful, nature-inspired meta-heuristic technique known as Fitness Dependent Optimizer (FDO). To show the efficacy of the proposed controller and the technique used, they have been tested on three different system models. Initially, a two-equal area of diverse source generation including reheat-thermal, gas, and hydro power system is considered. In the second scenario, the same power system model is used with addition of two non-linearities; Generation Rate Constraint (GRC) and Governor Dead Band (GDB). Lastly, multiple non-linearities including Governor Dead Band (GDB), Time Delay (TD), Generation Rate Constraint (GRC), and Boiler Dynamics (BD) have been considered to make the initial system more realistic and practical. The outcome from the proposed techniques is also compared with some recently meta-heuristic algorithms such as Teaching Learning Based Optimization (TLBO), Particle Swarm Optimization (PSO) and Firefly Algorithm (FA). From the results, it has been perceived that the proposed technique shows superior performance in respect of Overshoot (Osh), Undershoot (Ush) and Settling Time (Ts) of the system frequency.
Highlights
Power system is typically built from interconnection of various complex electrical networks composing of electrical generation, transmission and distribution system
In order to show the effectiveness of the proposed technique, it has been simulated on two area multi-source Interconnected Power System (IPS) with 1% step load perturbation (SLP) in Area-1 considering three different scenarios
In this research work, an improved form of Proportional Integral Derivative (PID) controller known as Integral Proportional Derivative (I-PD) controller has been designed and applied for multi-source of two area power system with diverse generation source such as reheat thermal, gas, and hydropower system
Summary
Power system is typically built from interconnection of various complex electrical networks composing of electrical generation, transmission and distribution system. A properly designed power system must be able to support the customer demands at all times, taking into account the load variation. A balanced power system composes of two components; active and reactive power. The active power is responsible for Automatic Generation Control (AGC) or Load Frequency Control (LFC) while the reactive power is called Automatic Voltage Regulator (AVR). For reliable and quality power supply AGC. The associate editor coordinating the review of this manuscript and approving it for publication was Ahmed A.
