How flexible is the energy storage system?
To address these challenges, the future power system must have sufficient flexibility. The Energy Storage System (ESS) is an important flexible resource in the new generation of power systems, which offers an efficient means to address the high randomness, fluctuation, and uncertainty of grid power.
What is energy storage allocation dynamic programming?
By combining the state transition equation and the DP basic equation, the proposed method culminates in the energy storage allocation dynamic programming model, which determines the optimal locations, capacities, and rated powers of ESSs, along with the construction cost.
Why should power system expansion be planned?
Due to the rapid electric load demand growth and economic or environmental restrictions, the power system expansion should be planned using modern tools such as Renewable Energy Sources (RESs) and Battery Energy Storage (BES) devices. The existing transmission lines more often are not able to transfer the required power to the demand side.
What is energy storage allocation dynamic programming (ESA-DP)?
The proposed Energy Storage Allocation Dynamic Programming (ESA-DP) model gives a certain degree of flexible ramping capability to each partitioning area, so that the flexibility is evenly distributed in the large-scale grid.
