This paper assesses operational impacts of the Continental European power plant portfolio on a harmonization of load-frequency control. The technical basics are presented together with an 18-area system of Continental Europe implemented in SIMULINK. The results reveal significant differences in frequency restoration among control areas. These differences originate from country-specific power plant...
Transmission of power from one area to other area in interconnected power system causes variations in both the system frequency and tie line power interchange. Load frequency control is one of the efficient ways to solve these kinds of problems. In this paper a three area system is considered i.e., area-1 with thermal power plant, area-2 with hydro power plant and area-3 with nuclear power plant....
Hydropower is emerging as a major contributor to the world energy requirement. It's inexhaustible, clean and has many other benefits as it doesn't encounter the problems of population displacement and environmental problems. However, it requires control systems to keep the frequency values constant. In this paper we develop a model of three-phase micro hydropower Plant (MHPP) using Takagi-Sugeno (TS)...
Frequency variation is a critical issue in power systems. With the recent developments in power sector, complexity and non-linearity of power system is increased to higher degree. Conventional controllers are designed considering linear power system models, therefore performance of these controllers may be not suffice the requirement of state of art. New strategies and controllers for controlling...
Promotion of power generation by locally available distributed generation sources is one of the solutions to present energy crisis. This paper focusses on integration of solar photovoltaic, mini hydro, diesel and battery energy storage system. Sources such as mini hydro and solar photovoltaic are clean, environment friendly and have ability to complement each other. The key intention of this work...
This paper deals with Automatic Generation Control (AGC) of two area power system where in each area has thermal, hydro and gas power generation. The analysis is aimed at finding the proper governor speed regulation parameter(R) and participation factors for each of the generator type. Optimum controller parameters have been obtained for the PI state feed back controller. Simulation results are presented...
As shown in many recent works, the load-frequency behavior can be represented by system frequency response models especially for an islanding process. In this paper, a frequency response model incorporating an under-frequency load-shedding scheme is presented for islanding power system simulations. The model was applied for a practical power system with both hydro and fossil-fired power generators...
AUTOMATIC generation control (AGC) has been used for several years to meet the objective of maintaining the system frequency at nominal value and the net tie line power interchange from different areas at their scheduled values. One of the main components of AGC is Load frequency control (LFC), one of the major requirements in providing reliable and quality operation in multi-area power systems. In...
The most studies of load-frequency control in power systems are done using linearized power system models. Those models may have nonlinearities within turbines and their governors, but generator dynamics and nonlinearities in tie-lines are mostly neglected. Generally, those models are only valid in the vicinity of the system's operating point. In this paper, the behavior of an advanced load-frequency...
The principle of fuzzy model reference learning control (FMRLC) is expatiated in this paper. The FMRLC approach is applied to a nonlinear dynamical model of hydrogenerator unit by adjusting or changing fuzzy rule-base. The simulation results are compared with PED control scheme with genetic algorithm (GA-PID) in both 2.5 Hz frequency disturbance and 30% load rejection. And the simulations indicate...
This paper presents the design of a robust PID controller for load frequency control of non-minimum phase hydro power plant using particle swarm optimization (PSO) enabled automated quantitative feedback theory (QFT). The plant model considered here is a dynamic model of power system that includes the turbine, governor, load and machine dynamics subjected to control the load frequency in accordance...
