Due to this operating cost distinction, storage unit s 1 is favored by the ESS agent, to discharge higher amounts of energy in the day-ahead market (42.19 MWh), comparing to the corresponding from the unit s 2 (26.25 MWh), thus leading to higher energy accumulation for storage unit s 2.
Models for agent-based flexibility management How can many distributed units in the power system be controlled in a coordinated manner to ensure a renewable energy supply? In a power system supplied by renewable energy, all PV and wind power plants, battery storage and electric cars, smart consumers and many other units must work together to support the supply.
Failing to control the growth of thermal power capacity will result in increased carbon emissions. (3) After 2030, energy storage''s role in balancing supply and demand grows. Storage capacity should align with renewable energy scale and the regional characteristics of wind and solar resources to prevent overbuilding and stranded assets.

Moreover, such a setup can determine the most suitable configuration and operation mode under the influence of various factors.
A blend of analytical and heuristic algorithms is applied to convert and solve the model. The case study demonstrates the effectiveness of the tri-level programming model proposed in this paper in describing the multi-agent energy storage configuration problem.
