Abstract

Systems and methods for interfacing renewable power sources to a power grid are provided. In certain systems and methods, at least one weather condition that may affect the power output of a renewable power source is identified. A potential impact of the identified at least one weather condition on the renewable power source is determined. Historical data associated with the impact of at least one prior weather condition on the renewable power source is accessed. An output of the renewable power source that is supplied to the power grid is adjusted based at least in part on the determined potential impact and the historical data.

Description

[0001] Cross references to related applications [0002] This application relates to the co-pending US patent application serial number ______ (Attorney Docket No. 19441-0375), which was filed on August 28, 2009 and is titled "Systems and Methods for Interfacing Renewable Power Sources to a Power Grid", the disclosure of this application is incorporated herein by reference in its entirety. Technical field [0003] The embodiments of the present invention mainly relate to renewable power sources, and more specifically to systems and methods for interfacing renewable power sources to a power grid. Background technique [0004] Renewable power sources such as photovoltaics (PV) or solar cells are used for power generation in a wide variety of applications. PV cells generally convert light, such as sunlight, directly into electricity by creating a voltage in a material when exposed to electromagnetic radiation. The output signal generated by the PV cell is a direct current (DC) signal...
