Problems solved by technology

Also, DG resources cannot be used as part of a microgrid if designed as a voltage source
This is due to small differences in instantaneous output voltage causing large amounts of current to flow and potentially damage DG resources

Embodiment Construction

[0020] The present invention discloses a system and method that facilitates a control strategy for a power electronics interface (PEI) of a distributed generation (DG) resource. Various examples of DG resources may include, but are not limited to: photovoltaic (PV) systems, wind turbines, battery storage units, and fuel cells. In particular, the present invention concerns the interaction between one or more PEIs and an alternating current (AC) power distribution system.

[0021] figure 1 is an example environment in which various embodiments of the invention can be practiced. shown figure 1 Including power station 102; one or more transmission units 104a, 104b and 104c (collectively referred to as transmission unit 104); one or more distribution units 106a and 106b (collectively referred to as distribution unit 106); microgrid 108; loads 110a and 110b (collectively referred to as loads 110); and distribution network 112. Additionally, microgrid 108 includes one or more PEI...

Abstract

The invention discloses a method and a system for implementing a control strategy for Distributed Generation (DG) units. The control strategy is implemented in such a fashion so that a DG unit behaves similar to a synchronous generator. The method also describes grouping of multiple DG units to form a micro grid by using a supervisory control agent. The micro girds may further be arranged in a hierarchy.

Description

[0001] This application was filed on October 21, 2011 as a PCT international patent application for the US company PETRA SOLAR, INC. where the applicant designated for all countries other than the United States is Hussam Alatrash, a Jordanian citizen and the US only Citizen Nasser Kutkut, This application claims priority to US Provisional Application Serial No. 61 / 455,556, filed October 22, 2010, the subject matter of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates generally to the field of electrical energy generation. More specifically, the present invention relates to a method and system that facilitates the control strategy of a power electronics interface (PEI) of a distributed generation resource. Background technique [0003] Today large amounts of electricity are generated by large centralized power plants using fossil fuels, hydroelectric or nuclear power and transmitted over long distances to end use...
