Micro grid power system
A micro grid power system includes a plurality of generator sets, a photovoltaic system, an external load, and a controller. Each generator set includes an engine and a sensor to determine a temperature of exhaust gases exiting the engine. The photovoltaic system includes a plurality of photovoltaic panels for generating power. The external load is powered by the plurality of generator sets and the photovoltaic system. The controller is configured to determine the external load, and control the plurality of generator sets to maintain the temperature above a threshold temperature. The controller is further configured to determine a remaining load which is the external load subtracted by a portion of the external load powered by the plurality of generator sets, and control the photovoltaic system to power the remaining load.
1. A micro grid power system, comprising:
a plurality of generator sets, each said generator set including:
an engine;
an exhaust stack coupled to the engine to facilitate discharge of exhaust gases exiting the engine; and
a sensor configured to determine a temperature of the exhaust gases in the exhaust stack;
an external load powered by the plurality of generator sets; and
a controller configured to:
determine an increase of the external load,
control the plurality of generator sets to meet the increase of the external load, and to maintain the temperature above a threshold temperature for each said generator set, and
distribute the increased external load between generator sets of the plurality of generator sets such that the temperature of the exhaust gases determined by the sensor of each said generator set is at or above the threshold temperature, and such that respective portions of the external load handled by generator sets, of the plurality of generator sets, that are operating prior to the distributing the increased external load are not increased upon the distribution of the increased external load.
2. The system of claim 1 , wherein the sensor is positioned proximal to an outlet of the exhaust stack.
3. The system of claim 1 , wherein the threshold temperature corresponds to a condensation temperature of a fuel used for operating the engine.
4. The system of claim 1 , wherein the controller includes a dedicated control unit for each generator set for controlling the generator set.
