انرژی‌های تجدیدپذیر و نو, 2020

Population growth and the country's need to move towards development, requires the optimal use of energy. Nowadays, the current energy systems of the country, use fossil fuels to meet this need. The limitations and exhaustibility of fossil fuels, the creation of various types of environmental pollutions, greenhouse gas emissions and global warming, that indicates the obvious disadvantages of the use of non-renewable energies, further underscores the need for faster movement towards using renewable energies. The lack of an efficient and optimal energy model and a defect in the structure of the energy systems of the country, is one of the main reasons why in spite of the awareness of the problems of non-renewable energies and its harmfulness it is still we use these energy baskets. Smart energy systems, considering each of the three main energy systems (electricity, heat, and transmission) interconnect each other, examines the energy system as a whole to provide an appropriate sol...

8th Conference on Sustainable Development of Energy, Water and Environment Systems, 2013

In this paper we launch the design of Smart Energy Systems through the 100% renewable energy system analyses and research behind the CEESA research project. The transition from fossil fuels towards the integration of more and more renewable energy requires rethinking and redesign of the energy system. Traditionally a lot of focus internationally is put on the electricity sector to solve the integration puzzle focusing on electricity storage technologies e.g. batteries, hydrogen storage and on (electricity) smart grids. In Smart Energy Systems the focus is integration of the electricity, heating and transport sectors, and on using the flexibility in demands and various short term and longer term storage in the different sectors. Such a redesign also entails that the Smart Energy System is comprised of a number of smart grid infrastructures for different sectors in the energy system, i.e. the electricity grids, district heating (cooling) grids, gas grids and fuel infrastructure.

Sustainable development remains a comprehensive and complex interplay between the population growth, urbanization, economical development, and the living environment. During the last few years, the concept of "sustainability" has become the common interest among the scientific community. An important criterion for the translation of "sustainability" into the action plan is the establishment of the compatible energy supply and applications. This transition to sustainable energy systems has to be initiated in the urban areas, with the total energy consumption of up to 75%, and the emissions of greenhouse gases of 80%. Today, approximately 50% of the world's population is staying in the urban cities, and the figure is expected to be exceeding 60% by 2025. In parallel to this development, the novel concept of "smart city", with the new integration of sustainable energy systems have been highly promoted. The present work was conducted to update the unique concept of smart cities, and the successive implementation of sustainable energy systems. The comprehensive profiles of the applications of a variety of green energy, including the solar, geothermal, wind, hydrogen fuel cell, and biomass energy are elucidated. Additionally, the available supporting practices, together with the major key barriers for the innovation of sustainable energy practice are outlined. 1 INTRODUCTION Sustainable development can be regarded as the development that meets with the present needs without compromising the advantages of the future generations. The concept of sustainability has gained popularity with major focus being placed on the developing cities with dense population growth, fast economic growth and huge consumption of a variety of resources. In parallel to this evolution, the unique concept of "smart city' has been established, with the integration of information, communication technology (ICT) network and smart energy systems as the essential components to sustainability. Energy, a stimulus of the sustainable development, is a supporting tool contributing to the successive implementation of the concept of "smart city". According to International Energy Agency, a 53% increase in global energy consumption is foreseen by 2030, consisting mainly 34.8% of crude oil, 29.2% of coal and 24.1% of natural gas. These growth trends have attracted an aesthetic concern connected to the limitations of sustainable energy supply, and the resulting competition of natural resources (Foo, 2015). Extensive researches have been directed to the exploration of renewable energy, to fulfill the global energy demand and ascertain the preservation of the natural environment. In particular, renewable energy has been put in the limelight in upgrading the efficiency of the existing power resources. Various efforts were undertaken to embark the development of renewable energy resources, notably solar, wind, geothermal, bioenergy, and hydrogen for energy generation in these smart cities. With the aforementioned, this present paper attempts to highlight the novel concept of smart cities. The unique linkages with the sustainable and renewable energy system, and the successive implementations of solar energy, wind power, geothermal, biomass and hydrogen are addressed. The supporting practices and major key barriers are outlined. 2 SMART CITIES 2.1 Conceptual understanding In early 1970s, the notion of "wired city", which stressed on the role of ICT network, was introduced to foster the rapid development of urban populations. The concept of "intelligent city", with the integration of cognitive sphere from "wired city", and primarily relies on top-down policies, was then introduced. This intelligent city vision excluded the element of the "people-centered" dimension. The emergence of "creative city" has highlighted the opposite trend (bottom-up participation), that relies mainly on the community-based and private sector initiatives, living labs and social entrepreneurship. Smart city is the hybrid model of both intelligent and creative cities (Ben Letaifa, 2015), with the consideration of "environmental sustainability"

This paper focuses on clean energy solutions in order to achieve better sustainability, and hence discusses opportunities and challenges from various dimensions, including social, economic, energetic and environmental aspects. It also evaluates the current and potential states and applications of possible clean-energy systems. In the first part of this study, renewable and nuclear energy sources are comparatively assessed and ranked based on their outputs. By ranking energy sources based on technical, economic, and environmental performance criteria, it is aimed to identify the improvement potential for each option considered. The results show that in power generation, nuclear has the highest (7.06/10) and solar photovoltaic (PV) has the lowest (2.30/10). When nonair pollution criteria, such as land use, water contamination, and waste issues are considered, the power generation ranking changes, and geothermal has the best (7.23/10) and biomass has the lowest performance (3.72/10). When heating and cooling modes are considered as useful outputs, geothermal and biomass have approximately the same technical, environmental, and cost performances (as 4.9/10), and solar has the lowest ranking (2/10). Among hydrogen production energy sources, nuclear gives the highest (6.5/10) and biomass provides the lowest (3.6/10) in ranking. In the second part of the present study, multigeneration systems are introduced, and their potential benefits are discussed along with the recent studies in the literature. It is shown that numerous advantages are offered by renewable energy-based integrated systems with multiple outputs, especially in reducing overall energy demand, system cost and emissions while significantly improving overall efficiencies and hence output generation rates.

This study presents an evaluation framework for the techno-economic-environmental (TEE) performance of the integrated multi-vector energy networks (IMVENs) including geothermal energy. Geothermal energy storage (GES) offers huge potential for both energy storage and supply and can play a critical role in decarbonising the heat load of smart multi-energy grids. The two most common types of GES, that is, high-temperature GES (HTGES) and low-temperature GES (LTGES), were modelled and integrated within the framework. This framework evaluates the impact of different low carbon energy sources including HTGES, LTGES, wind and Photovoltaics (PV) on the amount of energy imported from upstream, operational costs and emissions of IMVENs to meet the heat load of a region. The evaluation framework performs TEE performance analysis of any configuration of IMVEN representing future energy system pathways to provide a basis for well-informed design choices to decarbonise heat. The TEE evaluation framework was tested on a real-world case study, and several IMVEN configurations were designed and analysed. The results reveal that the most efficient, cost effective and least carbon-intensive configurations for meeting the heat load of the case study are the configurations benefitting from HTGES, from high penetration of heat pumps and from LTGES, respectively.
