Klepach L. Managing power consumption on cost criteria in MicroGrid

The development of renewable electricity is one of the priorities of Ukraine's energy policy - it is envisaged by the "National Renewable Energy Action Plan for 2020". The reorientation of local energy principles has become the basis for the emergence of the new MicroGrid concept. It is a concept of a fully integrated, self-regulating and self-renewing electricity system that has a network topology and includes generating sources, distribution networks, and consumers of electricity managed by a single, real-time information system. The concept of an energy system based on the principles of MicroGrid is that it transmits not only energy but also information. In this case, the consumer, in addition to energy, gets a number of opportunities to interact with the energy system, in particular, can more flexibly choose tariffs, plan energy consumption and, consequently, reduce electricity costs. Therefore, MicroGrid is a convenient platform for testing and implementation of electricity transmission. Electricity from renewable energy sources (RES) is generated, consumed and has its own cost depending on the type of source, energy quality and features of circulating energy flows in electrical systems and complexes - from private household to MicroGrid, Smart Grid, power plant and large generating plant . Thus, electricity can be considered as a commodity in the market. And, as for any type of product, it is necessary to consider three aspects of the product: the legal framework, economic feasibility and technical implementation of electricity transmission. That is why consideration of various interrelated aspects of electricity transmission is a very important task.
