Embodiment Construction

[0013] figure 1 is a block diagram of an example grid 100 . The grid is organized into a multi-level hierarchy including primary 102 , secondary 104 and local 106 levels. The power management systems 108a-d are coupled to the grid and configured to receive signals from the sensors 110a-f and inject or absorb real and reactive power from energy storage devices to compensate for grid events.

[0014] The main stage of the grid includes main generators 112a-b. The primary generator can be, for example, a coal fired power plant, a nuclear power plant, a wind power plant, a solar array and a hydroelectric power plant. The primary stage of the grid is connected to the secondary stage of the grid. One or more transformers step down the voltage between the primary and secondary.

[0015] The second stage includes a secondary generator 114 and in some implementations is the load. The secondary generator can be, for example, a coal-fired power plant that produces less power than th...

Abstract

A control system for an energy storage device is coupled to sensors on an electrical grid. The control system is configured to receive a measurement from each of the sensors. The control system determines, based on the received measurements, whether a grid event is a local event or a distributed event. The control system selects a response mode for controlling the energy storage device based on whether the grid event is determined to be a local event or a distributed event.

Description

technical field [0001] The present disclosure relates generally to managing power flow, and more particularly to managing energy delivery in an electrical grid in response to different types of events. Background technique [0002] Modern power systems must deliver energy efficiently and reliably. This is because people rely heavily on electricity. Electricity powers many devices such as computers, cell phones, lights, appliances and machines, all of which are integral to the lives of many citizens. As society's demand for energy increases, power system infrastructure needs to be improved to deliver increasingly important power resources in an efficient and reliable manner. [0003] Large power plants typically generate electricity and will send the electricity through the grid distribution system before it reaches the target load. However, power systems may experience problematic events, such as fluctuating power output of generators, significant changes in load, or phys...
