Surface temperature estimation for building energy audits

Apparatus and methods performing secure communications in an energy delivery system. Energy delivery systems may include phasor measurement units (PMU), phasor data concentrators (PDC) along with power generation, transmission and consumption equipment. The PMU and PDC may communicate in a grid network over secured wired or wireless communication protocols. Embodiments may include utilizing spread spectrum communication between PMU devices and PDC devices to sustain energy delivery functionality during a communications attack. Communications security may include a cryptographic key management scheme for secure PMU and PDC communication and identification. Embodiments may include clustering of PMU and PDC data for analysis and real-time presentation to grid operators. Embodiments may include clustering of PMU devices in a hexagonal geometry to provide for frequency reuse among devices with directional antenna.
