A process for detecting statistically significant changes in energy consumption patterns by monitoring for changes in the parameters to a parametric energy model. Two parametric models of energy consumption are created: the first being a model providing an initial base line of energy consumption, the second being a test model to be compared to the initial base model. Statistically significant changes are detected by using a difference score that compares the parameters of two models along with the uncertainties of each parameter to determine whether the differences in the parameters of each model indicate a statistically significant deviation in the energy consumption pattern.

An electric power distribution system is used with an electric power source. The electric power distribution system includes a first device exchanging first electric power with the electric power source. The first device exchanges the first electric power with a plurality of second devices and meters first electric energy corresponding to the first electric power. The second devices exchange the first electric power with the first device. Each of the second devices exchanges second electric power as at least part of the first electric power with a number of corresponding electric loads and meter second electric energy corresponding to the second electric power. A processor includes a routine that compares the metered first electric energy from the first device with a sum of the metered second electric energy from each of the second devices, and responsively determines proper or improper operation of the electric power distribution system.

The present invention discloses an intelligent electricity meter system with a light wallet, including a CPU, a metering module, a blockchain light wallet module and a communication module. By using a blockchain light wallet module, the present invention solves the problems that the electricity meter in the prior art cannot implement the peer-to-peer electricity transaction, and electric quantity collection, transaction and recording of the distributed wind photovoltaic and storage battery, and the demand for the energy Internet big data cannot be met. The distributed electricity generation and storage as well as the bi-directional metering of electric energy production and electricity consumption of an electricity user are implemented, such that the electricity quantity of a scattered intelligent microgrid may be metered, transacted and recorded. The distributed electricity generation side and utilization side make the microgrid more feasible economically by taking the intelligent electricity meter as an evidence of transaction charge.

An energy harvester for use in-line with a pipe to harness potential and kinetic energy of fluids flowing therein. Structure for the energy harvester may include a shaft and a blade extending radially therefrom. The shaft can penetrate a housing that operates as a pipe section to install the device in-line with pipe. The shaft can couple with an electrical generator. A load may connect with voltage terminals on the generator so that fluid impinging on the blades will rotate the generator to power the load, effectively harvesting power from the flowing fluid. In one implementation, a load control device that couples with the generator voltage terminals controls a pressure characteristic of the fluid, such as pressure drop, by applying an electrical load on the generator and controllably impeding rotation of the shaft.

A system for monitoring and wirelessly transmitting solar array parameters such as current, voltage and temperature in real time is primarily housed within a recombiner box. The system lends itself to retrofitting within some commercially available recombiner boxes. Signals emitted from the RF controller component of the system are received by a central processor, which includes a dashboard interface. Multiple systems in proximity can be linked to form a mesh network with one central processor.
