My name is Rajmund Drenyovszki. I am an assistant lecturer at the John von Neumann University (formerly Pallas Athene University and Kecskemet College) and a PhD student at the University of Pannonia in Hungary.

My research topic is: UTILIZATION OF CYBERPHISICAL SYSTEMS IN SMART GRIDS TO ACHIEVE HIGHER EFFICIENCY

One of the main issues in electricity networks is keeping an almost perfect balance continuously between electricity generation and consumption. Traditionally the balance is satisfied by the utilization of flexible but expensive generators, or the change of the voltage and frequency resulting in a low quality service, or in the case of oversupply the needless energy is wasted. However in the case of smart grid technology the balance can be satisfied by the control of the demand side, i.e. at the consumer side. Our approach tries to give an automatic user level solution to the short time balance problem of the electricity grid. The proposed method, called as Consumption Admission Control - CAC, estimates and shapes the probability distribution function of the aggregate power consumption of electricity consumers.

Basic idea of Call Admission Control The CAC algorithm is a function of the smart meter, which performs the admission control (enabling/disabling) of the appliances by such a way, that the probability distribution function (pdf) of the aggregate consumption satisfies the prescription of the service provider. As a result the CAC algorithm shapes the probability density function of the aggregate consumption of a given consumer. The success of the CAC approach is highly depends on the ratio of appliances that tolerate temporarily disabling (i.e. shifting the consumption to a later time). Many types of appliances can tolerate some delay e.g. executing the program of a washing machine later.
