System and method for management of a DC and AC bus microgrid
View Patent ↗Systems and methods are described herein for managing the operations of a microgrid module. The microgrid module includes transformers and/or power converters necessary for modifying the input AC or DC power sources to meet the required characteristics of the output power. The microgrid module further comprises a power management software module and a control software module installed on a microgrid computer. The power management software module receives business parameters such as prices from power contracts. The power management software module uses the parameters to create rules for applying to the operation of the microgrid module. The rules the power management software module creates are stored locally at the microgrid computer so that they can be quickly accessed by a control software module. The control software module uses the rules in combination with data collected from sensors installed in the physical circuitry layer of the microgrid module to control the operations of the microgrid module.
1. An apparatus for managing a microgrid module comprising:
a microgrid computer comprising
a power management software module processing a business parameter;
a local computer readable storage device storing a rule created by the power management software module from the business parameter;
a control software module using the rule stored in the computer readable storage device to send a command to a first controllable element to control the operation of the microgrid module;
a circuit layer comprising
an AC input bus coupled to an AC output bus and a first converter;
a DC bus coupled to a second converter;
the first converter coupled to the DC bus;
the second converter coupled to the AC output bus;
a first sensor coupled to the DC bus, the sensor sending data to the control software module; and
the first controllable element coupled to the AC input bus, the first controllable element receiving the command from the control software module.
2. The apparatus of claim 1 , wherein the control software module stores the data from the sensor in a remote computer readable storage device.
3. The apparatus of claim 2 , wherein the power management software module retrieves the data from the sensor stored in the remote computer readable storage device;
modifies the rule based on the data; and
stores the modified rule in the local computer readable storage device.
4. The apparatus of claim 1 , wherein the DC bus is coupled to one or more of a solar energy source, a wind energy source, a biofuel energy source, and a power storage device.
5. The apparatus of claim 1 , wherein the AC input bus is coupled to a utility AC power grid.
6. The apparatus of claim 1 , wherein the AC input bus is coupled to one or more of a solar energy source, a wind energy source, a biofuel energy source, and a power storage device.
7. The apparatus of claim 1 , wherein the AC input bus is coupled to a transformer.
