Influence of Different Strategic Decisions in Market Coupled Zones on the Energy System’s Expansion

Planning of development of energy systems today becomes closely connected to analysis of day-ahead energy markets, market coupling and dynamics of integration of both, renewable energy sources and demand response technologies. To investigate the influence of investments in production units on the commitment of units in the surrounding zones and quantify it, a scenario approach and optimization of marginal cost of energy produced is used in this study. To create a model of interconnected market zones, Dispa-SET software was used. A case study included several national energy systems connected in the common market, with base year model created in year 2016 for verification and future scenarios in 2030 created with different strategic decision made in each of the zones. Scenarios for each energy system represented unambitious strategy approach ; moderate approach and ambitious approach in relation to intensity of energy transition and the climate and energy goals of the European Union. Results demonstrate the influence of different strategic pathways in different zones, expressed through load hours of different energy production and storage installations in the investigated zone and neighbouring zones and over the border transmission of energy. Based on such results, conclusions can be made on the economic feasibility of new production and storage installations in different zones, as a consequence of their local strategic decisions. Also, the direction of energy transmission provides additional information about the benefits that certain zone had due to strategic decisions it decided to implement.
