Content available remote Security policy and good practice for implementation of smart grid solutions
PL
Smart Grid jest koncepcją i zarazem sposobem na złagodzenie braków infrastrukturalnych oraz przeciwdziałania skutkom rosnącego popytu na energię elektryczną. Jednym ze sposobów zapewniających wzrost efektywności zarządzania elektroenergetycznego jest wykorzystanie najnowszych rozwiązań komunikacyjnych. Rozwiązania takie zapewniają mniejsze zużycie energii, wyrównanie krzywej dobowego obciążenia, zmniejszenie strat dzięki automatycznego bilansowania energii i większe bezpieczeństwo transferu.

Smart Grid is both a concept and a way to mitigate infrastructural deficiencies and counteract the effects of the growing demand for electrical energy. One of the ways ensuring an increase in power grid’s management efficiency is utilization of the latest communication solutions. Such solutions ensure reduced energy consumption and leveling cur ve of daily load, decreased losses and – thanks to automated energy balancing – increased transfer security.

Development Of Electrical Power Systems And Their Integration With An Increasing Number Of Smart Automation Devices Compel To Undertake A New Approach To The Issue Of The System’s Security. Reliability Of An Electrical Power System And High Service Availability Are The Essential Characteristics Of Efficient Strategic Electricity Customers, I.E.: Large Industrial Facilities, Railway Transport, Medical Service Providers And Life-Saving Institutions. The Time Of Manual Or Automatic System Recovery After A Failure, Which Increases Its Security, Is Not Without Significance, Either. The Article Discusses The Issues Of Risk Assessment And Management, Including The Overall Process Of Analysis And Assessment Of Threat Probability In Electrical Power Systems.

In recent years, electric power systems, in order to improve their efficiency, are increasingly using the latest innovations in the field of information and communication technologies (ICT) starting from wireless communication and fiber optics systems. Both used for industrial automation purposes and complex data analysis. Those systems, year by year, have made use of more and more sophisticated communication algorithms leading to automatic management of energy distribution process as well as undertaking the system resuscitation tasks as a result of failure. The use of ICT communication equipment in electric power systems is certainly a big advantage, but it also entails some safety issues. The traditional understanding of smart grid cyber security involves the general requirements (placed on existing systems) as well as specific solutions for detection and intrusion prevention (for individual parts of the system infrastructure). Implementation of security policy in management process of the power system, with means of modern technical of digital information transmission, will increase efficiency and reliability of those systems.

Content available Security policy for low-voltage smart grids
EN
Smart Grid is both a concept and a way to mitigate infrastructural deficiencies and counteract the effects of the growing demand for electrical energy. One of the ways ensuring an increase in power grid’s management efficiency is utilization of the latest communication solutions by use of IT technologies. Such solutions ensure reduced energy consumption and evened 24-hour loads, decreased losses and – thanks to automated energy balancing – increased transfer security. Such solutions will directly translate into increased efficiency of the entire power grid. The present article contains an introduction to smart power grids, perspectives for their development in Poland, as well as an extended discussion of related issues concerning security on the organizational level.
