In this master thesis we will set out to create development scenarios for storage in the distribution networks. The thesis presents the technologies for storage of electric and thermal energy, suitable for distribution network level as well as direct installation at end consumers. After reviewing the possibilities of their use, which are interesting both for enhancing the stability of the system operation as well as for provision of services in the electricity markets, I shortly describe the economy of their use. In order to well define the scenarios, we will therefore focus on the key variables of their development. Key performance indicators are presented through which the results of the simulations will be evaluated. Four scenarios were constructed using the two key variables: activeness/passiveness of the users and technology/policy driven development. Listed scenarios will be used for simulations of grid development in the European project STORY.
