5 FAQs about [The first batch of photovoltaic energy storage combined operation]
How does battery energy storage connect to DC-DC converter?
Battery energy storage connects to DC-DC converter. DC-DC converter and solar are connected on common DC bus on the PCS. Energy Management System or EMS is responsible to provide seamless integration of DC coupled energy storage and solar. Typical DC-DC converter sizes range from 250kW to 525kW.
How does a DC-coupled storage system affect PV output?
DC-coupled system (right figure)—with shared 50-MW inverter—must shift storage output to lower-price periods to accommodate PV output. DC-coupled system value decreases by about 1% relative to independent PV + storage system. Impacts of DC tightly coupled storage systems are more significant.
How many mw can a PV & storage plant produce?
Combined output of independent PV + storage plant (left figure) is as high as 70 MW, which is possible because of the separate inverters. DC-coupled system (right figure)—with shared 50-MW inverter—must shift storage output to lower-price periods to accommodate PV output.
How does co-locating a solar inverter reduce the cost of deploying solar?
Coupling by co-locating storage and solar can decrease the overall net costs of deploying PV and storage (AC coupling). Further cost reductions are possible via sharing the inverter (DC coupling). This can reduce clipping but can result in non-optimal storage dispatch, especially if the storage capacity is sized close to the size of the inverter.
How does DC-coupling affect PV capacity value?
Result is a total capacity value of $7.5 million/year. DC-coupling causes no decline in capacity value, because the PV capacity credit (20 MW) plus the storage capacity (30 MW) equals the inverter capacity of 50 MW. Independent, AC-coupled, and DC-coupled (flexible charging) storage receives 7-year MACRS (Modified Accelerated Cost Recovery System).
