What are the operating models of energy storage stations?
Typically, based on differences in regulatory policies and electricity price mechanisms at different times, the operation models of energy storage stations can be categorized into three types: grid integration, leasing, and independent operation.
Is energy storage a single operating mode?
With the expansion of the energy storage market and the evolution of application scenarios, energy storage is no longer limited to a single operating mode. Depending on the location of integration, many countries have gradually developed two main market operating models for energy storage: front-of-the-meter (FTM) and behind-the-meter (BTM).
What are energy storage configuration models?
Energy storage configuration models were developed for different modes, including self-built, leased, and shared options. Each mode has its own tailored energy storage configuration strategy, providing theoretical support for energy storage planning in various commercial contexts.
Which energy storage mode is best for new energy plants?
Despite the extensive research on energy storage configuration models, most studies focus on a single mode (such as self-built, leased, or shared storage), without conducting a comprehensive analysis of all three modes to determine which provides the best benefits for new energy plants.
What is the energy storage configuration model in shared mode?
The energy storage configuration model in the shared mode is as follows. The upper game leader is the energy storage station, and the objective function maximizes the revenue: $$max C_ {share,leader} = sumlimits_ {i} {C_ {i,service} } - C_ {investor}$$
What are the different types of energy storage configurations?
New energy power plants can implement energy storage configurations through commercial modes such as self-built, leased, and shared. In these three modes, the entities involved can be classified into two categories: the actual owner of the energy storage and the user of the energy storage.
