Abstract

As renewable energy （such as distributed photovoltaic） is connected to the low-voltage distribution network on a large scale, the proportion of electronic equipment in grid-connected inverters continuous to increase, causing harmonic disturbance and dynamic impedance change of grid-connected systems, increasing the difficulty of measuring the operating state characteristics of distributed photovoltaic grid-connected systems. Therefore, an automatic tunning method of distribution network operating state under distributed photovoltaic access is proposed. Taking the subisland N-1 limit power loss rate and load balancing rate as state measurement indicators, the operating state of the distribution network is classified into different levels, the operating state evaluation results are calculated. Active and reactive power coordination optimization and tunning are realized by improving the particle swarm optimization algorithm. Factors such as the impedance ratio, voltage amplitude and equivalent reactance of the distribution network are considered. The stable tunning of cooperative operation is realized by state space and integral approach method. State space coordination control is introduced to improve the automatic tunning ability of distribution network. The experimental results show that the proposed method has high voltage stability level improvement and high operating stability state debugging sensitivity.
