Many control models and algorithms have been proposed to achieve better system quality, security, reliability, efficiency, loadability, and cost effectiveness. Early distribution systems are built based on centralized power generation which is named passive distribution system (PDS), where power flow is unidirectional. Nowadays, the topology of the distribution system allows for bidirectional power flow which is named active distribution system (ADS) due to the presence of active resources, such as distributed generations (DGs). The complexity of controlling each system depends on the topology and size of the network, as well as the control devices used. However, in general there are mainly two main control strategies used to control power networks: centralized and decentralized. This paper provides a review for both control strategies in the distribution system based on Volt/Var control techniques. It introduces the most commonly used techniques and algorithms in the literature for passive and active distribution systems. Moreover, it provides the reader with a comprehensive review on the common optimization techniques and the different objective functions used in terms of loss minimization, voltage deviation, and minimum control variable operation.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122836193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this setting, active residential load management can play an important role to help end-users optimizing the usage of energy resources (grid, local generation, storage and loads) to minimize the overall energy cost without compromising comfort. The scheduling of load control actions should take into account energy costs, end-users' preferences and requirements, potential dissatisfaction when the operation cycle of loads is changed, technical constraints, weather forecasts, the existence of local generation and storage systems. A multi-objective optimization approach has been developed to assist decisions weighing the minimization of the energy cost and the minimization of end-user's dissatisfaction associated with the implementation of management strategies. Due to the combinatorial nature of this model, an evolutionary algorithm has been designed to optimize the integrated usage of multiple residential energy resources considering a vast set of potential management strategies taking into account the end-user's profile regarding the acceptable balance between the cost and comfort dimensions. Those energy resources include the grid, local generation, shiftable loads, thermostatically controlled loads and storage systems (stationary and electric vehicle). The evolutionary algorithm makes the most of the physical characteristics of the problem to obtain results that can be implemented in practice with a mild computational effort. Results of case studies have shown that savings can be achieved with an energy management system based on this approach, although dependent on the end-user's preferences and willingness to accept automated control.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"2 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116798110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main difficulty in image enhancement is determining the criteria for enhancement and, therefore, more than one image enhancement techniques are empirical and require interactive procedures to obtain satisfactory results. In this paper robust image enhancement algorithms are discussed, implemented to noisy images and compared according to their robustness. The algorithms are especially able to improve the contrast of medical images, fingerprint images and selenography images by means of software techniques. When deciding that one image has better quality than another image, quality measure metrics are needed. Otherwise comparing image quality just by visual appearance may not be objective because images could vary from person to person. That is why quantitative metrics are crucial to compare images for their qualities. In this paper Peak Signal to Noise Ratio (PSNR) and Mean Squared Error (MSE) quality measure metrics are used to compare the image enhancement methods systematically. All the methods are validated by the performance measures with PSNR and MSE. It is believed that this paper will provide comprehensive reference source for the researchers involved in image enhancement field.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127645048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a dc-dc converter for large wide input-voltage range application is often used as the front-end converter in the microgrid. The boost and full-bridge converters are integrated to reduce the cost and filter by sharing the switches. However, voltage stress of the rectifier diode is high and difficult to be selected in the conventional integrated boost full-bridge converter, so it is not suitable for large wide input-voltage range application. Therefore, an improved integrated boost full-bridge converter is proposed. Voltage stress of rectifier diodes, voltage stress of switches, and size and weight of the input and output filters are reduced. Operating principle of the proposed converter is illustrated.

In developing countries with rapidly growing economies one of the main problem and obstacle for economic development is shortage of power supply. This makes it a contested resource among different socio-economic sectors. Therefore, distribution of power to different socio-economic sectors with overlapping power demands during power shortage requires careful and strategic decision making in order to maximize the socio-economic benefit that can be obtained out of limited power supply while maintaining equitable distribution. This research article proposed approaching power supply allocation problem during power shortage as game theoretic bankruptcy problem. Then the allocation of power during power scarcity among different socio-economic sectors using the classical bankruptcy allocation techniques was proposed. Each sector is characterized by its power demand. Such an approach could help make power allocation decisions which maximizes the socio-economic benefits from limited power supply by distributing it in a way that can be a base for efficient, reasonable and fair power supply management schemes during periods of power shortage.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114211806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To accomplish this task, different renewable energy based technologies, such as Solar PVs, wind turbines, electrolysers, hydrogen tanks and fuel cells are considered. The energy hub approach is used for the modeling, which enables the provision of smart grid services and allows the management of both the energy generation and the energy loads of an entire community. As a case study, a community consisting of a large distribution center and a residential complex is considered. The micro grid is responsible for meeting the electricity demands of the community as well as supplying hydrogen for the forklifts and hydrogen vehicles. The hydrogen can be used directly as fuel for a fuel cell forklift, or vehicle, and for the generation of electricity via vehicles for the bi-directional grid connection, which allows the option to supply electricity during peak hours by means of stored hydrogen energy.
