Abstract: A computer-implemented method for implementing an overlay network on peer-to-peer network to enable resource allocation that accounts for attributes and statuses of one or more nodes therein is provided. The computer-implemented method includes registering one or more nodes with the overlay network and executing overlay registration routing of the one or more nodes by building a routing table to cause node types to know about each other. Overlay sorting is executed between the node types based on corresponding characteristics.

Abstract: Techniques for detailed monitoring and evaluation of individual subsystems within solar photovoltaic power generation systems are provided. In one aspect, a method for monitoring a photovoltaic system having at least one array of photovoltaic panels and at least one inverter system configured to convert output from the panels from DC to AC includes the steps of: obtaining sensor data from the photovoltaic system; computing an efficiency of the panels and an efficiency of the inverter system using the sensor data; computing an aging parameter for the panels using the efficiency of the panels; computing an aging parameter for the inverter system using the efficiency of the inverter system; determining whether the aging parameter for the panels or for the inverter system exceeds a predetermined threshold level; and taking action if either the aging parameter for the array or for the inverter system exceeds the predetermined threshold level.

Abstract: Techniques for power sharing in DC networks using virtual impedance frequency droop control are provided. In one aspect, a method for power sharing in a DC network having multiple electrical energy generation sources connected to at least one load includes the steps of, at each of the electrical energy generation sources: generating a controllable DC voltage; superimposing a controllable AC signal on top of the DC voltage; regulating the AC signal using virtual impedance frequency droop control; and determining a desired DC voltage output using the regulated AC signal. The DC voltage can then be regulated to match the desired DC voltage output. A system for power sharing in a DC network is also provided.
