应用切比雪夫多项式滤波的高渗透率光伏分布式控制策略
Distributed Control Strategy for Photovoltaic Units with High Permeability Using ChebyshevPolynomials Filtering
摘要
Abstract
Distributed control requires only local communication and has good robustness and flexibility in the power control of the dispersed photovoltaic units.A distributed control strategy based on the discrete consensus algorithm,in which the upper layer strategy uses the consensus algorithm to optimize the output of photovoltaic to meet the total power demand and share the demand equally,while the lower layer strategy applies voltage-based control method whose reference point is obtained by quadratic interpolation.The convergence speed of proposed strategy will be slow when the number of photovoltaic curves becomes large.To improve the convergence speed,Chebyshev polynomials filtering is used in the consensus algorithm.The proposed polynomials filtering method is fully distributed and robust to the changing communication topology.A case study testifies to the effectiveness of the proposed distributed control strategy.关键词
