Load Demand Forecast of Organized Industrial Zone and Imbalance Cost Analysis
(IEEE, 2019) Hacer Sekerci; Sekerci, Hacer
This project aims an economic analysis by estimating the electrical load of an organized industry zone in Izmir Turkey and creating a scenario close to reality. The electrical load of the organizing industry was estimated by artificial neural network method using electricity consumption values. In this method a multilayer perceptron model use for feed-forward algorithm and for a backpropagation training algorithm Levenberg-Marquard algorithm is used. The results obtained by artificial neural network and multiple linear regression method were compared with each other.

Performance Assessment of University Buildings Based on Provided Thermal Comfort
(Institute of Electrical and Electronics Engineers Inc., 2019) Nurdan H. Yildirim; Hacer Sekerci Öztura; Sekerci, Hacer; Yildirim, Nurdan
Buildings and industry cover the largest share of total energy consumption. When the distribution of energy consumption in buildings is examined it is seen that the most important part is air conditioning systems. Therefore improving the energy consumption of air conditioning systems or using more efficient systems have great importance. The factors affecting the energy consumption of air conditioning systems are system type capacity design operation and climate conditions and user interventions.Yasar University is the first University having the TS EN ISO 50001:2011 Energy Management System Standard Certification in Turkey. Since the buildings and their systems are different in the Campus the new performance indicators are necessary to evaluate energy performance of the buildings. In this regard addition to existing energy metering system thermal comfort measurement devices were installed in some classes and offices in the campus.In this study performance assessment of two buildings in the Campus of Yasar University has been done based on their specific energy consumption and provided thermal comfort to the classes. Thus the relationship between energy consumption and thermal comfort in buildings is revealed and suggestions are presented to increase energy efficiency. © 2020 Elsevier B.V. All rights reserved.

The Determination of Optimal Operating Condition For an Off-Grid Hybrid Renewable Energy Based Micro-Grid: A Case Study in Izmir Turkey
(POLITEKNIK ELEKTRONIKA NEGERI SURABAYA, 2021) Sezai Polat; Hacer Sekerci; Polat, Sezai; Sekerci, Hacer
Nowadays off-grid systems which do not require grid connection investment instead of grid connected systems have become quite feasible. In this study a feasibility analysis was carried out for a hybrid energy system using solar and wind energy sources to supply to uninterrupted electricity demand of a region with 100 villas in Izmir Turkey. It has been shown that how changes cost of the hybrid energy system sizing according to the control strategies by using the HOMER software. In the paper two different control strategies are determined as Cycle Charging (CC) and Load Following (LF) and then the control strategies are compared. According to the results obtained as a result of the simulations it has been revealed that the research region to operate with CC can supply to the electrical energy demand with lower capacity system architecture. The CC was found to be more suitable for the research region than LF in terms of both Cost of Energy (COE) and Net Preset Cost (NPC).
