The current energy system will need to undergo profound changes in order to address the three main challenges of European energy policy: sustainability, security of supply and energy market liberalization. The increasing integration of renewable energy sources and the transition to a more sustainable energy system pose challenges for both society and the European energy system and its governance. The active role of consumers is particularly important in this transition. In order to address the transformation of energy systems and their management and the role of the consumer in this process, complex research is needed in order to study many social, economic and engineering aspects and perspectives. One of the most important aspects of innovation in the field of energy is the introduction of renewable sources. However, the production of electricity from renewable sources has one main negative aspect – the volatility and unpredictability of production. To address this problem, battery systems are increasingly being used, which store excess energy and put it into the grid during peaks in electricity consumption, thereby reducing the volatility of the production of power plants from renewable energy sources, increasing the security of electricity supply and contributing to balancing the electricity grid and maintaining electricity quality parameters. For these reasons, with the increasing popularity of small, private household systems (low-power solar power plants and low-capacity, private battery systems), this work examines how to effectively use these systems not only to meet the needs of the consumer, but also for balancing the electricity distribution network. The first part of the work reviews the possibilities and technologies of batteries and small private smart networks, examines the scientific literature related to the possibilities and methods of involving the user in the management of the electrical system. In the second part, with the help of “MATLAB” and “Excel” software, a study is carried out that models the operation of private micro-networks and the possibilities of providing flexibility services, looking at them from the user's perspective. As a result of the simulations, the main economic indicators are calculated, on the basis of which the economic assessment of the scenarios is subsequently carried out. |
