面向高比例新能源接入主动配电网的多层模型预测电压控制
Multilayer Model Predictive Voltage Control for High Proportion New Energy Integrated Active Distribution Network
摘要
Abstract
The integration of high proportion of new energy into distribution networks poses significant challenges for voltage control of distribution network.Traditional voltage control methods cannot ensure satisfactory control performance in scenarios with high penetration of new energy.Additionally,traditional voltage control relies on mechanical voltage regulation equipment,and frequent operation of these equipment significantly affects their lifespan.To address these issues,this paper proposes a multilayer voltage control method based on model predictive control(MPC).In the proposed method,mechanical voltage regulation equipment,such as transformers and shunt capacitors,is controlled in the upper layer with a longer control period,while active and reactive power outputs of distributed generations are rapidly adjusted in the lower layer with a shorter timescale.The objective of the upper-layer control is to reduce the number of operation of mechanical voltage regulation equipment,while the lower-layer control aims to minimize network losses and active power curtailment,ensuring the economic operation of the distribution network.The proposed method considers both the current and future states of the distribution network,ensuring that voltage operates within allowed limits under high penetration of new energy.Simulation results show that the proposed method can effectively address the voltage violation issues introduced by the high penetration of new energy in the distribution network,decreasing the system voltage mean square error from 3.9%to 0.97%.Additionally,the proposed method significantly reduces operation number of mechanical voltage regulation equipment,which is only 40%and 16.4%of those under traditional voltage control methods,respectively.关键词
