Abstract: The invention relates to a method, arrangement and computer program product for determining resiliency in a microgrid (10) comprising a number of assets (14, 16, 18, 20), where each asset is a different type of electric energy subsystem in the microgrid. The arrangement comprises at least one control unit (30, 32, 34, 36, 38) configured to obtain status data about devices (32, 34, 36, 38) used to control the assets as well as about communication resources of this control, determine, based on the status data, the health and availability of each asset to assist each of a plurality of functions for handling disruptive events in the microgrid and determine a resiliency (RI) of the microgrid in performing the plurality of functions, the resiliency being determined based on the individual asset health and availability of each asset (14, 16, 18, 20) concerning all the functions for handling disruptive events.

Abstract: The present disclosure relates to a method of controlling an electrical power network (1) comprising a distribution grid (3) of a grid operator (2) and a plurality of charging stations (5) for electrical vehicles (EV) (7). The method comprises maintaining a distributed ledger which is shared over a peer-to-peer (P2P) network (10) in which the grid operator, each of the plurality of charging stations and each of the EVs using said charging stations comprises a node in said P2P network. The method also comprises, by means of a consensus algorithm, updating the distributed ledger with tokens of digital information relevant to the electrical power network. The method also comprises controlling the electrical power network based on the digital information of the tokens in the updated distributed ledger.
