Tiivistelmä
Currently the amount of renewable energy resources is increasing in the energy system. To meet the changing requirements, grid structure and market mechanisms need to adapt to the new means of energy production. In this study, the main purpose is to explore alternatives of electricity market in microgrids. First of all, an overall evaluation of the changing energy system is provided, as well as an overview of the current electricity market of Finland. For localized electricity market, it is needed to have peer to peer (P2P) trading possibility which can be enabled for instance by Blockchain. Examples of three different Blockchain based microgrid energy markets are examined in order to have a better understanding of utilization of Blockchain in P2P trading. A localized market may require new or changed actors. The roles of these actors are described according to literature. However, they are used only as a guide to understand the individual actor’s activities in the market. In practice, roles can be changed or combined into different formations according to the situation.
Based on the gathered information, different alternative market models are created for microgrids. In theory, there can be a high number of possible scenarios for microgrid energy markets. However, in the study, six distinctive scenarios are determined according to ownership and operation of the microgrid, internal markets, and microgrids’ connections to the external market. For each scenario roles of the actors and devices are defined, their interactions are illustrated with figures and the balance mechanism is explained. As a result, the most outstanding result of the study is that there is not a single market model that can apply to all microgrids. With changing structures and expectations of the microgrid, optimum market model also changes.
