Self-consumption (PV system)

A PV “self-consumption” (SC) system maximizes the use of solar energy produced on-site and minimizes the usage of electricity imported from the grid. Loads are managed so they run during prime solar-production hours and, optionally, the PV-generated electricity can be stored for later use.

Self-consumption rate

Self consumption rate is defined by the ratio between the PV energy which is used directly or used for charging the battery and the overall produced PV energy.

Simulation

The representation of the energy behavior or characteristics of one system through the use of another system using a model where no pilot data from a specific region are available.

Smart Grid

Collectively; devices, practices and protocols that enable rich monitoring and situational awareness and flexible and robust control of various parts of or entire power systems under varying conditions. Among other objectives, Smart Grid is expected to reduce peak demand, increase energy efficiency and increase electric service reliability and power quality.

Smart meter

A device that records consumption of electric energy and communicates the recorded information back to the utility for monitoring and billing. Usually smart meters enable two-way communication between the meter and the grid.

State of Charge

The available capacity (in Ah) of a battery, expressed as a percentage of its rated capacity. It is defined as the percentage of the present capacity of maximum battery capacity.

Tags : SoC

State of Health

A measure of the battery’s ability to store and deliver electrical energy, compared with a new battery.

Sustainable Energy Plans

The key document in which the Covenant signatory outlines how it intends to reach its CO2 reduction target by 2020. It defines the activities and measures set up to achieve the targets, together with time frames and assigned responsibilities.
