This article describes the problems associated with distributed electrical power generation and the most frequent interruptions occurring in power grids. The most common methods of improving the quality of the power supply were analyzed and the possibilities offered by energy storages in this respect were considered. The operating parameters of an exemplary PV system connected to the power grid were analyzed. For this purpose, the model implemented in the Matlab/Simulink environment was used. Based on the conducted analysis and a review of the literature, conclusions were drawn and solutions were presented which could improve the quality and the reliability of power supply. The simulations conducted focused on the co-operation of individual photovoltaic, micro-installations, with rated powers of 12.2, 19.825, and 39.65 Kw in the power grid, which also corresponds to the co-operation of several, smaller micro-installations with low density.

The article presents the history of the development, and the reasons for the creation of the SEVESO Directive, with particular emphasis on the latest Directive 2012/18 / EU of the European Parliament and the Council. The SEVESO III directive imposes detailed requirements on the plant operators regarding their control against major accident hazards related to dangerous substances. Individual countries of the European Union apply various requirements (following SEVESO III or more rigorous ones) for industrial plants. In Poland, the requirements of the SEVESO III Directive have been implemented in the Environmental Protection Act, and its executive acts. The SEVESO III Directive requires that the citizens of a given country have access to information about high and increased-risk establishments. In Poland, this requirement is met through the website www.mapy.geoportal.gov.pl. People can find information on establishments posing a risk of a serious industrial accident. The article presents how to use the portal and what information can be obtained there.
