This document discloses a solution for a method of monitoring an electric power grid. According to an aspect, a method comprises: obtaining, on a basis of one or more physical stimuli generated endogenously in the electric power grid, a first set of measurement data associated with a first location of the electric power grid, the physical stimuli belonging to nominal or near-nominal operation of the electric power grid and generating at least one of voltage fluctuation and current fluctuation that exceeds at least one threshold; computing a grid strength of the first location of the electric power grid on the basis of the first set of measurement data; mapping the grid strength to a grid strength of a second location of the electric power grid on the basis of the first set of measurement data and correlation between electrical characteristics of the first location and the second location.

System for determining electric parameters of an electric power grid

Methods, computer software and apparatus for use in an electric power grid are described. Measurement data is received intermittently or continuously from a plurality of measurement units, indicating values of at least one measured characteristic at respective measurement locations. The at least one is characteristic is monitored, and it is determined, based on the monitoring, that there has been a change in electric power flow in the electric power grid. Responsive to the determination, component data is accessed relating to characteristics of components of the electric power grid involved in provision and/or consumption of electric power. Based on received measurement data relating to the change and the accessed component data, a power flow characteristic of the grid in a given time period is determined.

This document discloses a solution for a method of monitoring an electric power grid. According to an aspect, a method comprises: detecting one or more physical stimuli in the electric power grid; obtaining, while the one or more physical stimuli is effective, a first set of measurement data associated with a first location of the electric power grid; computing operational information such as a fault level of the first location of the electric power grid on the basis of the first set of measurement data; mapping the operational information to corresponding operational information of a second location of the electric power grid on the basis of the first set of measurement data and correlation between electrical characteristics of the first location and the second location.

Methods, and apparatus for determining a characteristic of an inertial contribution to an electrical power grid are described. A change in inertia in the electrical power grid based on one or more inertia measurements performed in a first time period is determined. On the basis of the determined change in inertia and data indicative of an inertia contribution characteristic of one or more energy production facilities and/or one or more energy consuming devices in the electric power grid, a characteristic of an inertial contribution to the electrical power grid is determined for a second time period different to the first time period.

An apparatus for location sharing may include a processor. The processor may be configured to access a point of interest and a geographic cell associated with the point of interest. In this regard, the geographic cell may include geographic cell boundaries. The processor may also be configured to receive location information. The location information may describe a location of a device. The processor may be further configured to determine whether the location described by the location information is within the geographic cell boundaries and associate the device with the point of interest in response to the location described by the location information being within the geographic cell boundaries. The processor may also be configured to share the association between the device and the point of interest via an online service. Associated methods and computer program products may also be provided.

Methods, and apparatus for determining inertia within a synchronous area of an electric power grid are described. A frequency characteristic relating to a frequency of electricity flowing in the electric power grid is measured, a magnitude relating to a power flow modulation is determined based on data relating to power characteristics of one or more power units arranged to consume electric power from and/or provide real and/or reactive electric power to the electric power grid, and a frequency response characteristic associated with at least one area of the electric power grid is determined on the basis of the measured frequency characteristic and the determined magnitude characteristic. This enables frequency response characteristics within a synchronous area of the electric power grid to be easily determined.

An approach is provided for service provider controlled communication security. A security platform receives a connection request from a client device. The security platform determines context information associated with the device, access network, a user of the device, or a combination thereof, and then processes and/or facilitates a processing of the context information to determine one or more encryption ciphers to offer for the session. Next, the security platform causes, at least in part, establishment of the connection request using, at least in part, the one of the offered encryption ciphers.

An approach is provided for optimizing energy consumption for wireless always-on connections. A radio management module buffers non-real time data and schedules the transmission of the non-real time data by a wireless device. The module also determines a communication type for carrying the non-real time data and initiates transmission of the non-real time data based on the schedule and the determined communication type.

An approach is provided for determining an optimal keep-alive time period. A request is received from one of a plurality of user equipments for a keep-alive timer value. A specific network information related to a network serving the one user equipment is determined. A keep-alive timer value is determined based on the network information and advantageously using statistical analysis.
