微电网加权熵变脆弱性评估及实时重构

Vulnerability Assessment and Real Time Reconfiguration of Microgrid Based on Weighted Entropy Theory

结合复杂网络和熵变理论,考虑微电网的静态结构特性和动态运行特性,提出了加权熵变脆弱性评价指标,建立了基于微电网脆弱性评价的实时重构数学模型。通过元胞蝙蝠算法和改进下垂控制策略对重构模型和实时控制系统进行求解和控制。算例结果验证了模型及策略的有效性。

Combining complex network with entropy change theory and considering structural property and dynamic operating characteristics of microgrid, an evaluation index of weighted entropy change vulnerability of microgrid is put forward, and a real-time reconfiguration model based on microgrid vulnerability evaluation is established. Using cellular bat algorithm and improved droop control strategy the reconfiguration model and real-time control system are solved. The effectiveness of the proposed model and control strategy are validated by results of CERTS system.
