Energy Management To Provide Multiple Services From Battery To Grid
(Institute of Electrical and Electronics Engineers Inc., 2024) Disiacik,I.; Ceylan, Oğuzhan; Zehir,A.; Zanaj,E.; Ceylan,O.
Batteries may provide ancillary services to the power network and thus can be used as a energy storage tool. In this paper, we examine the income of the battery owner, the amount of energy drawn from the battery, and the amount of change in the state of the charge (SOC) by considering different cases. For this aim, our study uses real data of frequency, voltage, load, energy market prices and house power production and consumption profiles. From the simulation results obtained we observe that the profit that battery owners can make as a result of using these services is of great importance for the energy market of the future and the battery to grid system is crucial solution for minimizing problems caused by abnormal frequency, voltage, load, etc. in the network. © 2024 IEEE.

Optimal Allocation of Distributed Generators and Mobile Battery Energy Storage Systems in Distribution System
(Institute of Electrical and Electronics Engineers Inc., 2023) Ahmadi,B.; Ceylan, Oğuzhan; Ceylan,O.; Ozdemir,A.
This research proposes an expansion planning frame-work that determines the optimal number, location, size, and type of distributed generators (DGs) and the number, capacity, location, and operation of mobile battery energy storage systems (MBESSs) in the distribution networks to improve the voltage profiles. The framework is applied to IEEE 33-bus and 69-bus standard test systems. The framework uses the advanced grey-wolf optimization (AGWO) developed to deal with mixed-integer nonlinear programming problems and the forward-backward sweep power flow method to determine the optimal control parameters defined for the problem. This study shows that the proposed framework enables the allocation and operation of DG and MBESS units to eliminate all voltage violations. Moreover, a clear roadmap is proposed for the size and location of DG units in the system and guidelines for the monthly location of MBESS. © 2023 IEEE.

Optimal Capacitor Sizing and Placement Using Dragonfly Algorithm: a Case Study in Kazakhstan
(Institution of Engineering and Technology, 2020) Baimakhan,O.; Ceylan, Oğuzhan; Şenyüz,H.; Sauchimov,A.; Ceylan,O.
This paper solves capacitor placement problem using a recently developed heuristic algorithm called as Dragonfly optimization algorithm. We aim to determine the sizes and the locations of capacitors by minimizing the voltage deviations and active power losses. For this aim, we utilized Dragonfly Optimization Model and applied on a modified real distribution system from Almaty, Kazakhstan. To be able to simulate different load conditions, we randomly created varied load conditions taking base case as reference point. Then, the capacities and node locations of capacitors providing smallest voltage deviations and active power losses are selected as solutions. From the simulation results we have observed that Dragonfly Algorithm successfully determines near-optimal locations and sizes of the capacitors. © 2020 The Institution of Engineering and Technology.

Validation of Wind Turbine Model Software Simulation Using Real Time Windspeed Measurements
(Institute of Electrical and Electronics Engineers Inc., 2023) Polycarpou,A.; Ceylan, Oğuzhan; Shiacallis,S.; Christofides,N.; Papadakis,A.; Papadopoulos,T.; Ceylan,O.
Based on the achievements regarding the 2020 targets, the Renewable Energy Directive established a new, higher target for 2030, reflecting a significant increase of interest for renewable energy sources (RES). As a result, various new software simulation packages, featuring models of RES, have been developed and being used in academia as well as in industry for research, educational or training purposes. In this paper Wind turbine (WT) characteristics and wind speed data obtained from a commissioned wind farm in Cyprus are used to implement a simulation model in two different software programs featuring RES simulation capabilities. Power System Computer Aided Design (PSCAD) is used to investigate the electrical power output of a WT model, and KYAMOS software is used to investigate the modelling of the blades, the resulting primary torque and the resulting rotor rotational speed. The investigation result novelty is the establishment of the ability of the proposed, under development, software program to satisfy the three required characteristics. Therefore, Deviation from measured values of the turbine characteristics is observed for both programs, user interface and blade modelling, and the potential of integrating results of one software into the other is investigated. © 2023 IEEE.
