What is distributed energy storage?

Distributed energy storage is an essential enabling technology for many solutions. Microgrids, net zero buildings, grid flexibility, and rooftop solar all depend on or are amplified by the use of dispersed storage systems, which facilitate uptake of renewable energy and avert the expansion of coal, oil, and gas electricity generation.

How does energy storage work?

First, energy storage can act as both generation (by injecting stored electricity onto the grid) and load (during its charging state). Second, energy storage can be controlled so it operates only when intended and with controllable power levels. Several states have begun exploring interconnection processes tailored to these unique characteristics.

How can distributed energy resource management systems help inverters?

Distributed energy resource management systems (DERMS) and/or ADMS may be able to aid in this effort. With proposed DERMS capabilities (Grid Management Working Group 2017), DERMS could modify inverter power factor (PF) and settings as well as dispatch or broadcast randomized response times for inverters, which would support these functions.

Will distributed photovoltaics increase in the future?

Deployment of distributed energy resources (DERs), in particular distributed photovoltaics (DPV), has increased in recent years and is anticipated to continue increasing in the future (GTM 2017, Labastida 2017). The increase has been particularly significant on certain systems.

Should energy storage systems be transparent and non-discriminatory?

As energy storage markets grow, transparent and non-discriminatory interconnection standards for storage—whether standalone or BTM energy storage systems paired with DPV (“solar + storage”)—can help ensure a timely, cost-effective, and efficient process for developers, customers, and utilities. Figure 15.

How should energy storage systems be reviewed?

Include provisions to address different energy storage configurations and clarify what level of review each type of system will undergo—Energy storage technologies can be deployed under different configurations, which impacts the level of review required to ensure safe interconnection to the grid.
