In this article, Load Frequency Control (LFC) of three area unequal interconnected thermal, wind and Hydro power generating units has been developed with ProportionalIntegral (PI) controller under MATLAB/SIMULINK environment. Further, the PI controller gains values that optimized using trial and error method with two different objective functions, namely the Integral Time Square Error (ITSE) an...

This paper presents a practical model for load frequency control (LFC) of two-area interconnected power system. The proposed model is a non-linear power system and is framed with thermal generating units including security constraint governor dead band imposed by the governor. A Proportional Integral Derivative (PID) controller is used for the design and analysis of the proposed model. The Part...

This paper discusses the inclusion of wind generation in load-frequency control (LFC) a hydro-wind power system through technique known as virtual synchronous generator (VSG), which makes static converters, connect farms to grid, emulate behavior real generator. In addition, is considered operate unloaded mode, having reserve deal with load disturbances. It was found that participation LFC, the...

Excessive load demand with reliability in power availability, demands for interconnection of large number of generating units over existing tie lines. Due to sudden change in demand, the power transfer over existing tie lines working close to their thermal limits results in low frequency power oscillations. Thus, in modern power systems the study of mitigation of these frequency oscillations is...

In this paper, two robust decentralised proportional integral (PI) control designs are proposed for load frequency control (LFC) with communication delays. In both methodologies, the PI based LFC problem is reduced to a static output feedback (SOF) control synthesis for a multiple delay system. The first one is based on the optimal H1 control design using a linear matrix inequalities (LMI) tech...

This paper presents the Load frequency control (LFC) of a multi-source power system with Redox flow batteries (RFB). The power system comprises non-reheat thermal, hydro and gas generating units. RFB is integrated to the LFC system to improve the dynamic responses. The proportional plus integral (PI) controller is designed using the PSO technique. Dynamic responses are obtained by giving 1% ste...

Load-Frequency Control (LFC) is an essential auxiliary service to keep the electrical system reliability at a suitable level. In addition to the regulating area frequency, the LFC system should control the net interchange power with neighboring areas at scheduled values. Therefore, a desirable LFC performance is achieved by effective adjusting of generation to minimize frequency deviation and r...

Renewable energy provides 20% of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It provides almost onefifth of the electricity in world. Hydropower is produced in more than 150 countries. The main objective of this paper is modelling and analysis of the effects of the power system stabilizer (PSS) for load frequency control (LFC) system ...

Modern day power systems are divided into various areas. The transmission lines that connect an area to its neighboring area are called tie-lines sharing power between two areas. Automatic Generation Control (AGC) as the name signifies it regulates the power flow between different areas while holding the frequency constant. Frequency control as a major function of automatic generation control i...

Load Frequency control (LFC) in power system is undergoing a lot of changes due to the rapidly growing demand and due to various renewable generation integration to the existing system. This work proposes an LFC scheme based on Fuzzy Logic Control for a hybrid wind-diesel power system. Therefore the objective of this LFC is to minimize system frequency deviations and tie line power changes. The...
