Abstract: A method and system for performing blackstart functionality from renewable generation and battery energy storage systems are disclosed. A plant may include a microgrid that includes one or more customer loads and that may provide power to a utility grid. Blackstart may be performed to restore operations to part or all of the plant or to external loads such as microgrid customer loads or part of the utility grid. In practice, blackstart may be performed in order to restore operation to the one or more feeders in the plant, such as to the generation sources within the plant, to restore power to the plant auxiliary loads, customer loads in the microgrid, and to provide power to different sections of the grid when transitioning from shutdown mode of operation. In this way, the method and system may automatically transition from a shutdown mode of operation to an islanded mode of operation.

Abstract: A method and system for transitioning between grid-tied and islanded modes of operation are disclosed. A plant may include a microgrid that includes one or more customer loads and that may provide power to a utility grid. The plant may include clean energy sources, such as DC-coupled photovoltaics and battery systems, as well as other types of clean energy generation and storage technologies. In certain instances, the plant may transition from grid-tied (in which the plant receives or provides power to the utility grid) to islanded (where the plant is disconnected from and does not receive or provide power to the utility grid), and vice-versa. The method and system may automatically transition between grid-tied and islanded without interruption of power to the one or more customer loads.

Abstract: An exemplary power system includes a DC power bus and a photovoltaic system connected to the DC power bus. An energy storage system is connected to the DC power bus and stores energy injected to the DC power bus by the photovoltaic system. A power inverter is connected to the DC power bus and converts power between the DC power bus and an AC connected load. The power system also includes a control system that receives power system data from one or more sub-systems and devices connected to the DC power bus, and controls, in real-time, one or more of the power inverter and the energy storage system to act as a load on the DC power bus based on the received power system data.
