摘要：
For micro-grid containingwind and solar powers, maximized usage of those clean powers is a significant control target of micro-grid energy management. Uncertainties brought by wind and solar powers make it difficult to use wind and solar powers without waste. Demand response (DR) is investigated for optimal use of wind and solar powers. A new DR algorithm called weighting coefficient queuing (WCQ) algorithmis developed based on modified coloredpower algorithm and state-queuing (SQ) model to control thermostatically controlled appliance (TCA) loads. It allows customers to choose different colors to represent response level of TCAs. WCQ algorithm works well to solvefairness problem that some specific customers' devices are controlled more times than others under SQ model. WCQ algorithm also provides good customer comfort. A micro-grid with 1000 air conditioners (ACs) is used as test example. Simulation result verifies effectiveness of the proposed control method. © 2015, Power System Technology Press.
