Statistical Process Control Method of Demand Side Management
The present invention is a method of “Demand Side Management” (DSM) that is intended to manage the increasingly chaotic nature of the power grid, and is designed to adapt to the future impact to the grid patterns caused by the ongoing introduction of renewable power generation sources, battery charging associated with the increasing number of electric vehicles, and future unforeseen developments, by utilizing “Statistical Process Control” (SPC) techniques. SPC is typically a method for controlling manufacturing process variation in a factory, analogously the present invention adapts SPC methods to help monitor the quality of the grid by treating said grid as if said grid were a process with varying levels of quality, to which the present invention can detect, anticipate and respond by making immediate and adaptive future scheduling decisions for the control of device loads, or generation, for the benefit of consumers as well as power companies.
SYSTEM AND METHOD FOR CONTROLLING LARGE SCALE POWER DISTRIBUTION SYSTEMS USING REINFORCEMENT LEARNING
A method for controlling a power distribution system having a number of discretely controllable devices includes processing a system state, defined by observations acquired via measurement signals from a number of meters, using a reinforcement learned control policy including a deep learning model, to output a control action including integer actions for the controllable devices. The integer actions are determined by using learned parameters of the deep learning model to compute logits for a categorical distribution of predicted actions from the system state, that define switchable states of the controllable devices. The logits are processed to reduce the categorical distribution of predicted actions for each controllable device to an integer action for that controllable device. The control action is communicated to the controllable devices for effecting a change of state of one or more of the controllable devices, to regulate voltage and reactive power flow in the power distribution system.

Blockchain distribution energy management with optimized balancing
A cyber-secure local electrical power market for a power grid with a utility operator transmitting power where a group of participating nodes within the distribution network operate together through respective computers on a blockchain architecture. The participating nodes have controllable resources with controllers in operative communication within the blockchain architecture, such as controllable generators and controllable loads. Decentralized market software operates on computers within the blockchain architecture and shares blockchain datasets that include financial information associated with the controllable resources and operating states of the grid. One or more of the computers in the blockchain architecture calculates Locational Marginal Pricing (LMP) across the participating nodes according to the set of financial information and determines a set of energy service orders corresponding to LMP for the controllable resources to change their operating states. The computers also preferably calculate an energy balance with the transmission system in determining the energy service orders.
