Abstract: Electricity price prediction plays a vital role in energy storage system (ESS) management. Current prediction models focus on reducing prediction errors but overlook their impact on downstream decision-making.
In general, they conclude that storage provides only a small contribution to meet residual electricity peak load in the current and near-future energy system. This results in the statement that each new storage deployed in addition to the existing ones makes the price spread smaller, see Figure 16, and, hence, reduces its own economic benefits.
Conclusions This article studies the allocation of energy storage capacity considering electricity prices and on-site consumption of new energy in wind and solar energy storage systems. A nested two-layer optimization model is constructed, and the following conclusions are drawn:
This study aims to evaluate how market designs can affect the contribution of energy storage to electricity economics and decarbonization, from early to deep decarbonization stages. The proposed open-source framework can be used by researchers and policymakers to assess emerging technologies and policy incentives.
If is within the power supply capacity of the interconnection line, the external power grid should consider charging the energy storage system while supplying electricity; When is less than zero or greater than zero and less than , this situation mainly relies on the energy storage system to maintain the balance of .
A new approach to discuss future electricity storage cost is introduced by McPherson et al. ( 2018 ), using the integrated assessment mode MESSAGE to include the uncertainties of VARET provision and abatement cost.
