Increasing renewable energy integration to grid requires inertial support to improve frequency stability of the power system. Inertial support of renewable energy systems requires hardware verification in order to test practical limitations and absence of dynamical grid simulators makes verification studies more challenging. In this study, a test rig which is composed of a DC motor, an AC synchronous generator and an external flywheel, is developed in order to provide a platform in which dynamic properties of an actual power plant can be simulated in the laboratory conditions. A 4 kVA power plant simulator with a field exciter and a speed governor is developed with 1kVA buck converters. The frequency response of the test bench is controlled in parallel with the computer simulations in Digsilent Powerfactory environment. The developed test rig is a low cost and simple solution aimed for experimental studies regarding inertial support of renewable energy systems or power system frequency studies.

Design and control of PWM converter with LCL type filter for grid interface of renewable energy systems /
Kantar, Emre; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2014)
This thesis involves the PWM and control unit design and simulation for three-phase PWM converter widely used for grid-interface of renewable energy systems, motor drives, etc. The study involves selecting the LCL filter parameters, switching frequency, the PWM method, the cost-effective feedback controlled algorithm, etc. for the converter. The design is verified by means of detailed computer simulations. The study considers the normal and unbalanced grid conditions, which may occur in the grid operating c...
An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies
Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01)
The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the ...
Evaluation of Grid-Connected PV Converter Power Module Technologies in Terms of Efficiency, Initial Cost, and Return on Investment Time
Oztoprak, Oguzhan; Hava, Ahmet Masum (2019-01-01)
The voltage source converter (VSC) of the grid connected photovoltaic (PV) systems is the most technological component in a PV system and contributes to 5-15% of the whole investment. As the cost and energy efficiency of a VSC are two factors that determine the total system economics, the system total cost of ownership (TCO) should be optimized during the VSC design. This paper provides a design methodology for grid connected VSCs considering TCO, the return on investment (ROI) and payback period (PP) as th...
A METHOD FOR TECHNICAL ECONOMIC-ANALYSIS OF SOLAR HEATING-SYSTEMS
TASDEMIROGLU, E; ARINC, F (Elsevier BV, 1988-01-01)
The necessity for technical-economic analysis of solar energy systems is obvious when assessing their feasibility vis-á-vis conventional alternative systems. Optimum magnitudes of the installation parameters should be defined under the required economic conditions. In this study, the optimization procedure was chosen so as to maximize the total accumulated saving throughout the economic lifetime of the system. The annual solar heating fraction of the system is assessed using the f-chart method which can be ...
Design and implementation of a 200w microinverter for grid connected photovoltaic energy conversion system
Kavurucu, Semih; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2014)
As one type of the grid-connected photovoltaic energy conversion systems, micro-inverters (MI, also known as Module Integrated Inverters, MII) are typically designed for residential applications with energy capacities of 3-5 kW and less, in order to provide PV module level energy generation, plug-N-play operation, minimization of the shading effects occurring on the PV module, and flexibility of installation. For the micro-inverter system which can be designed employing variety of topologies, interleaving f...
