Intelligent Cost Analysis of Smart Photovoltaic Energy Storage Containers

Why should you invest in a PV-Bess integrated energy system?

With the promotion of renewable energy utilization and the trend of a low-carbon society, the real-life application of photovoltaic (PV) combined with battery energy storage systems (BESS) has thrived recently. Cost–benefit has always been regarded as one of the vital factors for motivating PV-BESS integrated energy systems investment.

What is the investment cost of storage systems?

The investment cost of the storage systems includes both energy and power costs. Additionally, to assess the environmental benefits of the planning optimization and operation optimization proposed in this paper, it is necessary to calculate the carbon emissions of the electricity consumed by the system.

Does electrical battery storage improve PV self-consumption?

A study carried out by Wang et al. on the technical and economic assessment of PV-battery systems revealed that although the application of the electrical battery storage led to enhancing the PV self-consumption, the payback of the PV system alone is short compared to the scenarios in which the battery system is integrated as well.

What is the cost-efficient size of a battery energy storage system?

Hence, the cost-efficient size of the battery energy storage system increases as the battery market prices drop equal to 2 kWh for the scenario in which the battery system’s market price is equal to 200 €/kWh and reaches over 8 kWh when the market prices ideally drop to around 100 €/kWh.
