Abstract

Systems and methods for coordinating selective activation of a multiplicity of emergency power generation equipment over a predetermined geographic area for distribution and/or storage to supply a microgrid of electrical power for a substantially similar geographic area.

Claims

1. A method for power generation and management, comprising:

providing a central controller and a distributed power generation system for providing emergency back-up power supply for a microgrid;

wherein the distributed power generation system comprises at least two types of equipment for providing electric power;

communicatively connecting the distributed power system with the central controller;

the central controller optimizing power generation timing, management, storage and distribution to the microgrid;

the central controller coordinating selective activation of the at least two types of equipment for providing electric power.

2. The method of claim 1, wherein the central controller is a Price Resource Management System (PRMS);

wherein the PRMS comprises a monitor device, a database, an analyzing device and at least one server computer, a device interface, and at least two controllable device;

wherein each of the at least one controllable device is connected to each of the at least two types of equipment for providing electric power respectively.

3. The method of claim 2, further comprising:

tracking wholesale energy market price in real time;

storing wholesale energy market price; and

analyzing whole energy market price based on predictive modeling;

generating power instructions when a predetermined threshold market price is reached based on predictive modeling of real time wholesale energy market price;

facilitating and producing communication of power instructions to at least one of the at least two controllable device; and

enabling or disabling the power flow from at least one of the at least two types of equipment for providing electric power.

4. The method of claim 3, further comprising analyzing data indicative of electricity remaining on a per power storage device basis;

wherein the at least two types of equipment for providing electric power comprises at least one power storage device.

5. The method of claim 1, further comprising the central controller collecting data including local microgrid metering information, user interface information, microgrid resource and commercial information, microgrid island condition alarm, critical alarm signals from utility, commercial and resource information from the markets and utility, and regulatory and environmental data.

6. The method of claim 1, further comprising selectively activating the at least two types of equipment for providing power to the microgrid when the public power grid experiences high demand for power supply.

7. The method of claim 1, wherein the at least two types of equipment for providing electric power comprises at least one power generator and at least one energy storage device.

8. The method of claim 1, wherein the at least two types of equipment for providing electric power comprises at least two different types of power generators selecting from the group consisting of solar arrays, natural gas generators, propane generators, diesel generators, and combinations thereof.

9. The method of claim 1, wherein the at least two types of equipment are operable to provide electric power only within the microgrid.

10. The method of claim 1, wherein the at least two types of equipment are operable to sell electric power to the public power grid.
