    LOAD FREQUENCY CONTROL OF A GAS TURBINE POWER PLANT IN RESPONSE TO A SUDDEN DISTURBANCE WITH A BATTERY ENERGY STORAGE SYSTEM (BESS)
    (2023-07) Nader, Kawa Abbas Nader
    In recent periods the world, we have seen the required need for an increase in the demand for the production of electric power and the increase in the expansion of building electric power production stations and electric transmission networks by a large rate of 50% in recent years, as well as the problem of frequency identification and frequency disturbance that occurs within the network transmission lines. And the value of the impact that occurs on the systems of producing electric energy from the systems of gas turbines and thermal turbines and the increasing demand for clean renewable energies, and it also has problems that cause symptoms in the conduct of transmission and production processes and interconnected electric power systems and provides a frequency equation by building interconnected electricity networks with equal and stable frequency and its solution and return to the natural frequency, and the relationship between production and consumption must be properly managed [1]. The output is higher if the frequency goes up, and if the frequency goes down, then the net is stable. In the end, the frequency stays constant. The active electrical outputs of the power generation system are controlled for regulation in such a way that load frequency management or automatic output control are terms used to describe the regulation [2,3]. Load frequency control consists of two systems: basic and auxiliary frequency control. The main frequency control loop of a synchronous generator consists of a speed limiter and a control circuit [4]. The error caused by deterioration in frequency and connecting line power can be managed solely by the primary control. The obtained speed regulator is given a second control by adding a signal proportional to itself and its integral. to control load frequency on an electrical system. In this research, a single-zone electrical system was studied, then a two-zone electrical system, despite the great limitations in increasing and decreasing electricity production during regular activity. To enhance the response of the basic control of the electric power production system [5]. This progress should be successfully represented in the use of gas turbine models as well as power system simulation tools. The study adds to a comprehensive study of engine frequency control concepts for power generation systems (vertical engines and gas power turbines), as well as advances in their design in the traditional analysis of power systems tools [6]. In this research, a gas turbine power system diagram model is built for one and two regions to show the comparison with the addition of a PID controller in its usual state and without the PID controller by using the MATLAB controller program. Adding a building model integrating the battery energy storage system BESS with the gas turbine system simplified to demonstrate the idea of solving the frequency problem in the future by using the charging and discharging system in case of frequency disturbance, restoring the frequency to the normal state, and extracting and comparing the results of frequency equality must be provided to connect interconnected electricity networks today to ensure equality and maintain a balance between production and electric power transmission networks. When frequency disturbance increases a lot, production will decrease in order to preserve the safety of production systems from falling. Control units lose active power in the case of synchronous generators to keep the turbine from activating the protection system to prevent damage and protect the equipment. This configuration is referred to as load frequency control or automatic production control. The load frequency control loop consists of the main and auxiliary frequency control cycles. The main frequency control cycle involves the use of a synchronous operation generator to regulate the speed limiter. Because the main management is insufficient, power line hesitation and contact deterioration occur, and it is integrated with a fault signal proportional to the speed regulator by adding a secondary control. This paper considered how to control the load frequency of the electric power systems of gas engine installations [7]. It was unclear which had greater performance in an electrical power system. The proportion of energy from renewable sources (RS) in electricity networks has increased in recent decades. New electricity systems will have less inertia and be more difficult to regulate because of sporadic and changeable green energy that is challenging to send because of its shifting characteristics. As a consequence, greater grid flexibility is needed to maintain system dependability. To satisfy this demand, new technologies that include energy storage systems using batteries BESS are being extensively discussed [8]. It's thought that it's highly advantageous to provide a quick and accurate response in frequency control services with BESS, especially in inertial situations. Changes in power networks have a significant impact on the sizing, charge-discharge control, and lifespan of a BESS offering frequency control service. As a consequence of this, deciding throughout the investment phase is a very hard subject [9]. In our research, the network frequency data was evaluated by evaluating the optimal size, age, and technical economy of the BESS that provides the load frequency control (LFC) tool. First, the BESS design with an LFC power system was created for this purpose. Secondly, the developed technology calculates the number of charge and discharge cycles of the BESS as well as the life of the BESS and the ability to degrade depending on the frequency deviation. Finally, the economic analyzes of BESS in the light of investment were carried out in one of the research chapters. Finally, the main objective (LFC) is to control the electrical power generation of a generator within a given area in response to changes in system frequency and turbine line load. (LFC) helps to maintain the planned system frequency and link line power transmission with other locations within the mentioned limits. Conventional controllers are slow and do not enable the controller builder to adapt to changes in the working conditions and linearity of the generator unit drive. When the load requirements of a unit of production change, there is a short-term imbalance in the real power input and final output. Externally, they are energy storage batteries system BESS [10]. The mechanism is used to compensate for the imbalance of electricity. Battery energy storage systems can successfully reduce frequency oscillations caused by large load disturbances [11-12]. Power devices that store energy are affected by sudden load changes in energy needs. This paper contrasts conventional controls with a BES system both qualitatively and numerically in LFC for a normal two-zone connected power system. This study confirms and discusses the superior performance of BESS over conventional controllers.
