In this paper, automatic generation control (AGC) of two area interconnected power system having diverse sources of power generation is studied. A two area power system comprises power generations from hydro, thermal and gas sources in area-1 and power generations from hydro and thermal sources in area-2. All the power generation units from different sources are equipped with speed governors. A...

This paper proposes an algorithm for transmission cost allocation (TCA) in a large power system based on nodal pricing approach using the multi-area scheme. The nodal pricing approach is introduced to allocate the transmission costs by the control of nodal prices in a single area network. As the number of equations is dependent on the number of buses and generators, this method will be very ti...

In the past few decades, increasing growth of wind power plants causes different problems for the power quality in the grid. Normal and transient impacts of these units on the power grid clearly indicate the need to improve the quality of the electricity generated by them in the design of such systems. Improving the efficiency of the large-scale wind system is dependent on the control parameter...

This paper proposes a design of Artificial Bee Colony (ABC) algorithm based Proportional plus Integral controller using Area Requirement (AR) Criterion for the Load Frequency Control of a two area multi unit interconnected thermal reheat power system without and with Gas Turbine unit. The system was simulated and the output responses of the frequency deviations, tie-line power deviation and con...

In this paper, Load Frequency Control (LFC) of isolated single area and two-area re-heat inter-connected thermal power system has been carried out by the classical controllers i.e. I, PI and PID; and implemented on the system at 1% step load perturbation under nominal loading conditions. The system responses have been simulated in MATLAB R2010a. Responses of deviation in frequencies, deviation ...

In this paper a fuzzy proportional-integral-derivative controller (FPIDC) is proposed for load frequency control of two-area interconnected power system with generation rate constraint (GRC). The FPIDC is developed as a set of heuristic control rules, and the control signal is directly deduced from the knowledge base and the fuzzy inference mechanism rather than adaptation of the parameters of ...

This paper presents the usage of sliding mode Control algorithm for the load frequency control in power systems. A sliding mode based load frequency controller is applied to a two-area power system. Non-reheat and reheat Thermal turbines are distributed in these two areas respectively. The nonlinearities such as governor dead band and generation rate constraint are included in the block diagram...

This article presentes a PID controller for two area power system equipped with both automatic generation control and automatic voltage regulator loops. The research has been done to control two area power systems with PSO optimized self-tuning PID controller. The comparison between different controllers and the suggested PSO based controller illustrates that the proposed controller can generat...
