Energy storage complicates such a modeling approach. Improving the representation of the balance of the system can have major effects in capturing energy-storage costs and benefits. Given its physical characteristics and the range of services that it can provide, energy storage raises unique modeling challenges.
To address the challenges presented by the complex interest structures, diverse usage patterns, and potentially sensitive location associated with shared energy storage, we present a multi-agent model for shared energy storage services that takes into account the perspectives of different actors in distribution networks.
Case 1: In a multi-agent configuration of energy storage, the DNO can generate revenue by selling excess electricity to the energy storage device. This helps to smooth and increase the flexibility of DER output, resulting in a reduction in abandoned energy.
The method involves three agents, including shared energy storage investors, power consumers, and distribution network operators, which is able to comprehensively consider the interests of the three agents and the dynamic backup of energy storage devices.
In summary, configuring and sharing an energy storage device among multiple agents, in consideration of their respective interests, can lead to more efficient utilization of the device. 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.
