What is a SoC-dependent energy storage model?
We first define an SoC-dependent energy storage model in which the power rating, efficiency, and discharge cost depend on storage SoC. We describe how to incorporate SoC-dependent energy storage model into multi-period optimiza-tions, which we will use as a benchmark for comparison.
Can SOC be used as a constraint in energy storage?
In Hu et al. (2018b), by using the SOC of the energy storage unit as a constraint, the energy storage device is made to provide inertia support for the system with the service life taken into account, but removing the SOC hastily because the energy storage device is in the limiting operation state will lead to system instability.
What is a new model for bidding and clearing energy storage resources?
Abstract—This paper introduces and rationalizes a new model for bidding and clearing energy storage resources in wholesale energy markets. Charge and discharge bids in this model depend on the storage state-of-charge (SoC). In this setting, storage participants submit different bids for each SoC segment.
What is a lithium-ion battery state of charge (SOC)?
The accurate estimation of lithium-ion battery state of charge (SOC) is the key to ensuring the safe operation of energy storage power plants, which can prevent overcharging or over-discharging of batteries, thus extending the overall service life of energy storage power plants.
Can energy storage change bids based on price/opportunity?
The energy storage cannot change bids according to price/opportunity cost variation within hours and submits averaged bids to the system operator instead. The single-period model with 1-segment bids (RTD-1) loses 9.6% more profit than RTD-5.
What is a SoC-independent storage model?
In the SoC-independent storage model, we use constant parameters assume the charge/discharge power rating of 0.25 MW (normalized according to 4-hour energy storage with 1 MWh capacity), one-way charge/discharge efficiency of 90%, and marginal discharge cost of $20/MWh for all seg-ments.
