A system configured per this disclosure can use identify a power network, the power network comprising generators, transmission lines, and loads, and receive a model of the power network. The model of the power network can include: models of the generators modeled as differential equations, and models of the transmission lines and the loads modeled as algebraic equations. The system can convert, via a processor, the algebraic equations of the models of the transmission lines and the loads to additional differential equations, then combine, via the processor, the differential equations and the additional differential equations, to yield combined differential equations. The system can then iteratively solve linear equations, via the processor, associated with the combined differential equations, to yield solutions, and output the solutions as part of a power simulation of the power network. | 2020-03-19 |
20200091765 | METHODS AND SYSTEMS FOR ASSESSING HOSTING CAPACITY IN A DISTRIBUTION SYSTEM - Methods and systems are described for determining a distribution system's hosting capacity for distributed power generation. Hosting capacity may be assessed on a feeder-by-feeder basis. Performing a hosting capacity assessment may include randomly selecting spot load points in a feeder as candidates for installation of distributed power generation sources. The hosting capacity assessment may be repeated a number of times to ensure optimal results and to correct for any violations of system performance parameters caused by an addition of distributed power generation at a given spot load point. | 2020-03-19 |
20200091766 | Systems and Methods for Dynamic Power Routing with Behind-the-Meter Energy Storage - A system includes a flexible datacenter and an energy storage unit that receives and stores power from one or more grid-scale power generation units. The energy storage unit and the flexible datacenter are connected behind-the-meter to the power generation unit(s) such that they are not typically subject to grid transmission and distribution fees. By various methods, behind-the-meter power is routed between the power generation unit(s), the energy storage unit, the flexible datacenter, and/or the grid based on a variety of conditions and operational directives. | 2020-03-19 |
