Abstract

Load prediction is necessary in VQC, because if the variation tendency of voltage and reactive power can be forecasted, the system can analyze and control in advance. There are many algorithms for load prediction. This paper presents an improved control method based on very-short-term forecast. The voltage and reactive power data queues are acquired from electric line with high speed, then the values after a certain time is predicted adaptively using improved least-square method. With load prediction involved in, higher sensitivity and better effect of the control can be achieved when the reactive power changes greatly
