6 FAQs about Profit analysis of policies related to shared energy storage

How a shared energy storage system works?

A two-stage model describing the storage sharing among stakeholders is developed. Storage sharing contribution rate is defined to inspire stakeholders to join share. An incentive mechanism is designed based on the asymmetric Nash bargaining model. Shared energy storage system ensures the economic feasibility of all participants.

Does a shared storage system have a complementarity of power generation and consumption?

In this context, considering the complementarity of power generation and consumption behavior among different prosumers, this paper proposes an energy storage sharing framework towards a community, to analyze the investment behavior for shared storage system at the design phase and energy interaction among participants at the operation phase.

What is shared Energy Storage (SES)?

As a new paradigm of energy storage industry under the sharing economy, shared energy storage (SES) can effectively improve the comprehensive regulation ability and safety of the new energy power system.

Are shared energy storage rates correlated with shared charging/discharging power?

In the shared energy storage mechanism proposed in this paper, the contribution rates of all prosumers are positively correlated with their shared charging/discharging power, that is, the greater the shared charging/discharging power, the more the cost-saving of prosumers.

How does sensitivity analysis affect shared energy storage investment capacity?

Through sensitivity analysis, the reduction of battery cost will lead to the decrease of total cost and the increase of shared storage investment capacity, while the increases of electricity price and carbon tax will lead to the increases of shared energy storage investment capacity and total cost.

What is a demand side energy storage sharing framework?

A demand side energy storage sharing framework with energy capacity and power capacity sharing is proposed, which introduces the transaction process and profit allocation method of the shared energy system.
