SYSTEM AND METHOD FOR INTEGRATING AND MANAGING DEMAND/RESPONSE BETWEEN ALTERNATIVE ENERGY SOURCES, GRID POWER, AND LOADS

摘要

A system, method, and apparatus for local demand response between alternative-energy power-generators, traditional controlled-energy power-generators, and power-consuming loads coupled to a DC bus are disclosed. As a DC bus operating voltage fluctuates between a minimum bus operating voltage to a maximum bus operating voltage, it triggers different power-generators and different power-consumers each having staggered control voltage ranges that enable them to come on-line or go off-line, depending on the bus operating voltage, thereby providing distributed, autonomous and self-regulating demand response performance. Loads vary from opportunistic loads at high alternative-energy generation scenarios, to necessary loads powered by backup or traditional power-generators for low alternative-energy generation scenarios. Safety limits are provided with voltage limits and foldback limits.
