    Possible Contributions of Smart Grids to Regional Development of Countries
    (Ieee, 2018) Kaygusuz, Asim; Tuttokmagi, Ozge; Keles, Cemal; Alagoz, Baris Baykant
    Although smart grid concept has recently become a subject of academic studies; impacts of this concept appear in many areas of engineering. Today, the smart grid concept involves many subjects from the efficient use of electrical energy resources to the planned and programmed consumption of energy, from the integration of distributed renewable energy sources into the system to the domestic productive consumers (prosumers), which are much related to local or regional development. Smart grid concept, which emerges a product of interdisciplinary studies ranging to many fields of engineering such as power systems, control, artificial intelligence and communication, can be briefly viewed as a development process towards the internet of energy. Especially in recent years, the decrease in reserves of fossil-fueled energy sources has led researchers to find out new energy sources, more efficient and ecological production and distribution methods. In these studies, the energy sources, which are renewable, sustainable, and economical have become major priorities due to reducing carbon emissions. However, the scope of smart grid studies has been continuously enriched and it has begun to include the fundamental components of production-centered sustainable development models, which are the providing of low-cost production supplies, continuity of these supplies, efficiency in production and consumption, generation based on renewable or recyclable resources, and applications of ecological generation and consumption methods. In this context, the positive effects of smart grids on the regional development are expected to occur in the following topics: Smart city applications, intelligent transportation, renewable and local energy generation, smart homes and building concepts, energy efficient cities, control of carbon footprint, automated electricity, gas, water and waste networks, loss and leakage control, application of demand side energy management system to reduce power consumption, self-healing electricity distribution, smart energy pricing, smart energy storage are some emergent topics that can contribute to sustainable regional development models. Because, modern grid components developed within the scope of smart grid are expected to support sustainable production models via smart energy management and increasing efficiency, reducing the energy costs, improving energy continuity. In this study, a projection for possible contributions of smart grid concept with its continuously expanding scope to the sustainable regional development is discussed under several major headings.

    Smart Grids and Industry 4.0
    (Ieee, 2018) Tuttokmagi, Ozge; Kaygusuz, Asim
    Since the beginning of the Industrial Revolution, the concept of Industrial Revolution in the 4th/Industry 4.0 which is a new turning point in the technologies used, is in every field as well as in the energy field which is considered as the key point of all revolutions. It is aimed that energy generation, transmission and distribution are more efficient and highly reliable together with the next generation software and hardware which is the result of this concept. It has been seen that existing networks can not be enough to achieve this goal. At this point, flexible, reliable, clean, sustainable and highly efficient electric energy due to smart grids come into play. However, due to the increase in demand for electricity due to increase in population and industrialization, the dependence of electric energy on production resources, the availability of renewable energy sources in a dispersed geographical structure and the loss and leakage are becoming more important in our country. The Cyber-Physical System, the Internet of Things, M2M (machine to machine), etc components are used in the energy field, especially in intelligent network systems, resulting in intensive use of technology at every stage from power generation to end-user distribution point. This includes better system operation, reduced costs, increased energy efficiency, reduced greenhouse effect, reduced downtime with reduced downtime, reduced loss /leakage rates, improved energy quality, better management of production and storage systems, intelligent meter reading and load management and real-time supply-demand management. Industry 4.0 / 4. Industrial Revolution and smart grids have many common aspects such as optimization, automation, efficient use and management of energy, intelligent production, everything internet. In this study, the development process of the Industrial 4.0 revolution in the world and in our country will be examined and the interaction with these process smart grids will be examined.

    Transient Stability Analysis of a Power System with Distributed Generation Penetration
    (Ieee, 2019) Tuttokmagi, Ozge; Kaygusuz, Asim
    In recent years, while fossil fuel prices have increased, these fuels have reduced to access. More importantly, it has reached an irreversible point in climate change. This situation has led to increasing importance of renewable energy resources, notably wind and solar energy. In particular, developments in technology and efforts to implement smart grids increase the share of renewable energy sources in energy generation. Due to this increased share, it has caused some changes in the power system. The most important of these changes is the power system stability, which plays a vital role in system planning and operation. These sources have tended to leave the grid in the event of a failure. Also, variable generation features always pose a risk for system stability. In this paper, IEEE 9 bus power system is used to investigate the behavior and risks of these resources with variable generation structures under various fault scenarios.

    Transient Stability Analysis of Power Systems with Distributed Generation
    (Ieee, 2019) Tuttokmagi, Ozge; Kaygusuz, Asim
    In recent years, distributed generation based on renewable energy has been popular due to environmental and economic concerns. Moreover, it is expected that the integration of distributed generation will increase with the developments over smart grid technologies. When this increase is small, the effects of distributed generation on the power system dynamics can ignore. On the other hand, if the level of integration is higher, it affects the dynamic behavior of the whole power system. In addition to the amount of integration, it is possible to face problems in the power system stability due to renewable energy sources with low inertia constant and uncertain feature. In this study, the effects of distributed generation based on renewable energy are investigated about power system stability. To investigate this effect, the IEEE 30 bus power system reorganized with distributed generations such as wind and sun by using the MATLAB program. Stability scenarios were produced and the stability responses of the power system were analyzed.
