Demand response capabilities and supporting technologies for electrical products Part 3.5: Interaction of demand response enabling devices and electrical products - Operational instructions and connections for grid-connected electrical energy storage (EES) systems
|Publication Date:||21 June 2016|
(a) applies to electrical energy storage (EES) systems that-
(i) do not contain a demand response enabling device (DRED);
(ii) have a demand response interface intended to connect to a DRED;
(iii) have a low voltage, permanently wired connection to the grid (whether single-phase or three-phase); and
(iv) are capable of importing energy from the grid, exporting energy to the grid, or both.
(b) specifies a set of operational instructions to control the demand response of EES systems;
(c) specifies methods of connecting the demand response interface to the DRED; and
(d) provides methods of testing to verify compliance. EES systems covered by this Standard include, but are not restricted to-
(i) electrochemical storage systems (e.g. batteries);
(ii) mechanical storage systems (e.g. flywheel);
(iii) electrical storage systems (e.g. capacitors); (iv) uninterruptible power supplies (UPS);
(v) thermal and chemical systems; and (vi) generation systems that are dispatchable.
An EES system may also meet the definition of an inverter energy system as defined in AS/NZS 4777.2.
NOTE: Examples of EES system configurations are given in Appendix E.
An EES system complying with this Standard may also have additional interfaces and other means of achieving demand response.
This Standard does not cover any other electrical product within the scope of AS/NZS 4755.3 series Standards.
NOTE: If compliance with this Standard is made mandatory by the relevant Australian and New Zealand regulatory authorities then any exclusions of EES system types, limitations on storage capacity, energy input or output or other criteria for limiting regulatory scope will be covered in the relevant regulations. In the event of any such regulatory limitations, this Standard can still be used voluntarily for EES systems outside the regulatory scope.
