摘要： A distributed energy resource (DER) may store electrical power from an AC circuit and discharge stored electrical power to the AC circuit. A DER may be coupled to the AC circuit via a plug inserted into a receptacle coupled to the AC circuit, and a load device may be plugged into the DER via a receptacle of the DER. The DER may pass AC power from the AC circuit to the load device, and may draw additional power from the AC circuit to charge an energy storage circuit of the DER. The DER may also discharge stored energy into the AC circuit and/or power the load device directly.

摘要： A method includes a power supply system receiving a first request for a first quantity of power for a first time period from a first unit. The system generates a first quote based on an available power generation capacity, environmental factors and a forecasted level of power consumption. The system transmits the first quote to the first unit. The system receives a second request for a second quantity of power for a second time period. The system generates a second quote based on the same factors as the first quote. The system transmits the second quote to the second unit. The value of the first quote and the value of the second quote are set to discourage demand in a first mode and to encourage demand in a second mode to maximize efficient operating levels of the power generation sources in both the first mode and the second mode.

摘要： The present invention relates to a voltage source converter based DC connection method and a control method for implementing a system for maintaining respective different frequencies (multi-frequencies) by reflecting load quality levels of respective microgrids when multiple stand-alone microgrids are connected to each other in which voltage source converters (VSCs) installed at connection points of the microgrids for effectively controlling respective microgrids having different frequency control ranges present an effective control method based on a concept using normalizing frequencies of unit microgrids to be similarly applied in an islanded operation mode of multiple grid-connected microgrids as well as multiple stand-alone microgrids to avoid the same frequency criterion and enable an economic operation to which the load power quality level of the microgrid is reflected, thereby minimizing a transient to stably operate a microgrid system.

摘要： A system for continuously generating baseload electrical energy entirely from renewable resources and transmitting the generated electrical energy to a transmission grid includes, in combination, a first energy generation device for continuously generating electrical energy output, which has a bio-mass fuel supply requirement for generating the electrical energy. One or more additional energy generation devices provide, as available, intermittent electrical and thermal energy for substituting, or supplementing, the electrical energy output of the first energy generation device, and for supplementing the fuel supply requirement for the first energy generation device. A switching device ensures a least-cost generation of baseload electrical energy from the generating system by selectively using the output of the first energy generation device or, as available, the one or more additional energy generation device for substituting, or supplementing, the electrical output of the first energy generation device, and selectively supplementing the fuel supply requirement of the first energy generation device providing, at a minimum, a baseload electrical energy output exclusively from renewable energy resources. A redundant supply of combustible bio-mass fuel assets are assured by a bio-mass harvesting and logistics system which supplies such fuels directly from the source to the first energy generation device for combustion. Effluent gasses containing CO2 from bio-mass combustion are sequestered in a body of fluid containing micro-algal bodies and light-emitting sources for causing, by photosynthesis in the presence of CO2, an increased mass of algal bodies by absorption of the CO2 and the emission of free oxygen. The increased mass of algal bodies are removed from the fluid body and used for the production of bio-diesel fuel. A method of operating an entirely renewable sourced electric power generation and transmission business is also provided.
