First, a model of life cycle cost-benefit is established to calculate various costs and benefits of energy storage. Then, the combination of genetic algorithms is determined, which is applied to the inner and outer layers. Finally, the proposed optimal configuration strategy is simulated with a Benchmark low-voltage microgrid.
The economic benefit indicator is the usage cost of energy storage. In the shared and self-built modes, the actual owner of the energy storage is the new energy power plant itself. Therefore, the usage cost of energy storage is equivalent to the construction investment cost and operational cost, which is the full lifecycle cost.
