Does ESS affect electricity price?
The supply curve in the New York Independent System Operator (NYISO) day-ahead energy market is modeled to evaluate the impact of ESS on electricity price. The operation and degradation cost is, however, set to be $1/MWh, which is significantly less than the practical cost .
What is a user-side energy storage device?
The user-side energy storage devices are treated as a single unit, which is called a distributed energy storage device.
What is electric power supply chain?
Generally, the electric power supply chain is the whole chain process from the provision of raw materials, to power generation, transmission, transformation, distribution and to power consumption.
