Benefits of technology

The present invention relates to a way to manage power production. The technical effects of this invention include increased efficiency, control, and optimization of power production. These features can be realized through a method and apparatus described in the text and described in more detail in the accompanying figures.

Problems solved by technology

DGs may be subject to degraded levels of input power from these renewable resources due to events such as weather events; for example, wind turbines are affected by reduced levels of wind, and photovoltaic (PV) modules are affected by shading events such as cloud coverage.
Sudden changes in input power levels may cause DG output power changes that exceed ramp rates required by utility companies.
Economics of such large scale installations are frequently driven by the cost of the necessary energy storage as well as the lifetime of the storage systems.

Embodiment Construction

[0015]FIG. 1 is a block diagram of a distributed generator (DG) system 100 for generating power in accordance with one or more embodiments of the present invention. This diagram only portrays one variation of the myriad of possible system configurations. The present invention can function in a variety of distributed power generation environments and systems.

[0016]The system 100 comprises a plurality or DG arrays 1501, 1502, . . . , 150M, collectively referred to as arrays 150. Each array 150 comprises a plurality of DG sub-arrays 1011. . . 101n, collectively referred to as sub-arrays 101, although the number of sub-arrays 101 may differ from array to array. The arrays 150 may all be owned by a single owner, or alternatively different owners may each own one or more of the arrays 150. Similarly, sub-arrays 101 within an array 150 may all be owned by a single owner or different owners may each own one or more sub-arrays 101.

[0017]Each sub-array 101 comprises a plurality of inverters 1...

Abstract

A method and apparatus for controlling power production. In one embodiment, the method comprises determining a predicted weather event; determining a predicted power production impact for a distributed generator (DG) array based on the predicted weather event; and controlling power production from one or more components of the DG array to compensate for the predicted power production impact.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 885,737 filed on Oct. 2, 2013, which is herein incorporated in its entirety by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Embodiments of the present disclosure relate generally to power production and, more particularly, to controlling power production based on predicted weather events.[0004]2. Description of the Related Art[0005]Distributed generators (DGs) generate power using one or more types of renewable resources as inputs. DGs may be subject to degraded levels of input power from these renewable resources due to events such as weather events; for example, wind turbines are affected by reduced levels of wind, and photovoltaic (PV) modules are affected by shading events such as cloud coverage. Sudden changes in input power levels may cause DG output power changes that exceed ramp rates required by utility companies.[0006]For l...
