考虑交互功率控制的微网经济运行
Economic Operation of Micro-grid Considering Regulation of Interactive Power
摘要
Abstract
The control of interactive power fluctuation between micro-grid and the public supply network was studied to analyze its impact on the operational cost of micro-grid. Taking into account the power flow restrictions, we proposed a multi-period scheduling strategy to realize the economic operation of micro-grid under various constraints on power fluctuations. To minimize operational cost of micro-grid, the imbalance price mechanism was introduced into the optimization of energy storage and load side management with the optimal contract size. We also studied the effect of transmission capacity, curtailment of wind and solar power on the control strategy and operational cost of micro-grid. The modified IEEE RTS-24 and FREEDM system model were taken as an example to verify the correctness and feasibility of the proposed method. The simulation result validated that the energy management strategy of micro-grid based on demand side response increased system operational benefit and developed the flexibility of regulation on tie-line transmission power, which discounted the influence of power fluctuation of distributed generation on upstream systems. This paper can also offer reference for micro-grid’s smooth integration into public supply network and its extensive applications.关键词
