A growing number of distributed generators (DG) in the utility networks is causing more and more problems related to voltage variations in the network and reactive power drawn from the HV network. The so called 'traditional' ways of connecting and operating DGs which are prescribed in the national rules of some European countries or in the EN standards are simply not good enough for overcrowded distribution networks. Fixed set reactive power of the DGs or even setting of the DG power factor to 1 are not the solutions to the mentioned problems. In order to achieve a good solution, DG must be able to regulate its reactive power in such a way to help maintain the allowed voltage level in the network at the minimum reactive power drawn from the HV network. The simulation of a practical case of connection of a photovoltaic power plant is made using different reactive power regulation techniques. Network hosting capacity is given for different reactive power regulation concepts. © 2014 IEEE.

The concept of SmartHome and SmartGrids integration comes to a technologically superior solution which actively connects energy consumers, distributors, retailers and other stakeholders into a mutual symbiotic relationship. The main benefits for customers are mainly reflected in lower monthly energy bills at a desired level of comfort, while the concept allows distributors to better manage the power grid and retailers to optimize energy purchases. The concept provides to distributors, retailers and other third party service providers a fundamental platform to develop new packages of energy supply and additional advanced services, including active energy management. The concept also deals with cyber-security principles, which need to be taken into account due to cyber-crime and privacy issues. © 2013 IEEE.
