چکیده مقاله :

Power systems are a complex system, which to control them in steady state, different control loops are needed. Load changes affect the frequency of electrical networks. Frequency stabilization (FS) is very important due to the increasing penetration of renewable energy sources in power systems. The main task of load frequency control is to keep the system frequency according to the specified nominal value and to maintain the correct amount of exchange power between the control areas. In this paper, load frequency control (LFC) in single-area power system (SIPS) is studied and simulated. Each area has a steam generating unit with a reheat steam turbine. The system equations are expressed in the state space and the system model is determined based on the transfer function. The simulation results have been obtained using Matlab software. The simulation results show the effect of reheater's parameters on the transient dynamic behavior of the system.
