Summary In today's world striving for efficiency in every sector, especially power generation and distribution, smart grids emerge as the solution for efficiently meeting the increasing demand. They adjust themselves to optimally deliver energy at the lowest cost and highest quality possible. The grid successfully makes use of renewable energy resources, electric vehicles, and smart pricing techniques in its attempt to achieve energy efficiency. It also promotes a greener environment by striving to reduce greenhouse gas emissions. Information communication technology (ICT) helps the grid in collecting consumption data from the consumers and in sharing tariff information. ICT also helps to gather information about the status of the grid with regard to aspects like power quality, faults etc. The purpose of this paper is to review recent literature with a view to comprehensively present the technologies employed in the smart grid for achieving energy efficiency and the challenges involved therein.

Abstract. Intelligent electric networks make it possible to remotely control switchings, thus preventing overloads and enhancing reliability of power supply to consumers. In the paper, the daily reconfiguration of a primary distribution network is considered as a means to reduce energy losses in the network. An algorithm applied for the reconfiguration is based on the methods of the theory of graphs and includes a high-speed program for load flow calculation. The research is focused on the impact of renewable generation and active demand with loads changing depending on daily variation in electricity price on the reduction in losses at reconfiguration. An algorithm is proposed to optimize load curves of load-controlled consumers. The calculation of probabilistic load flows is applied to assess the impact of the uncertainty of nodal power forecast on energy loss reduction at reconfiguration. The results of the research demonstrate the effectiveness of the proposed approaches, and are illustrated by a 33-node test distribution network.

Original scientific paper The application prospects of wireless sensor networks (WSN) are very broad due to their characteristics of convenience, low cost, accuracy. Wireless sensor networks have potential applications in many fields, such as business, smart home appliances, industry. Wireless sensor networks are considered to be one of the most influential technologies today. The power industry is not only related to the livelihood of individuals, but also to national security. At present, the development of the power industry has reached a bottleneck. One of the methods to break through the bottleneck of the development of the electric power industry is by combining the wireless sensor networks with the electric power industry and building a smart grid. Due to various reasons, the data generated by the wireless sensor networks may be lost, and the missing data will have a great impact on the detection of power data and the construction of the smart grid. The power data generated by the wireless sensor networks has both temporality and spatiality. In this paper, we propose a fusion algorithm to deal with the missing data in wireless sensor networks. Experimental results show that the proposed algorithm can effectively estimate the missing power data in wireless sensor networks.

Moguće ih je primijeniti u mnogim područjima kao što su poslovanje, inteligentni kućni uređaji, industrija. Smatra ih se jednom od najutjecajnijih tehnologija danas. Električna energija se ne odnosi samo na zaradu za život pojedinaca već i na nacionalnu sigurnost. Trenutno je razvoj energetske industrije stigao do uskog grla. Jedna od metoda za razbijanje uskog grla u razvoju energetike je kombiniranje bežičnih senzorskih mreža s elektroindustrijom i izgradnja inteligentne mreže. Zbog raznih se razloga mogu izgubiti podaci koje generiraju bežične senzorske mreže i ti će nestali podaci imati veliki utjecaj na pronalaženje podataka o energiji i izgradnju inteligentne mreže. Podaci o energiji koje generiraju bežične senzorske mreže imaju i temporalnost i prostornost. U ovom radu predlažemo fuzijski algoritam koji se bavi podacima koji nedostaju u bežičnim senzorskim mrežama. Eksperimentalni podaci pokazuju da se predloženim algoritmom mogu učinkovito procijeniti podaci o energiji koji nedostaju u bežičnim senzorskim mrežama.Kljućne riječi: bežične senzorske mreža; inteligentna mreža; metoda fuzije; nedostajući podaci
