Abstract:To meet the load demand for electricity, traditional distribution network simply increase the capacity of transmission and distribution power, which always could not guarantee a reasonable return for distribution companies. And the active technologies of active distribution network such as active planning, active control and active management can improve the utilization of the transmission and distribution device, reduce the cost of construction, but also reduces the income from electricity sales of distribution company. With the development of the electricity reform, the effect of active technologies to the economic benefits of distribution companies has become the focus of financial evaluation for distribution companies. This paper in-depth analyzes the multiple effects of active technologies to the economic benefits of distribution network.and proposes a quantitative calculation method. According to the traditional financial evaluation process, this paper takes a typical distribution network in case, analyzes its economic benefit considering the active technologies such as active planning, active control and active management, then analyzes the uncertainty of the key factors affecting the economic benefits. This paper explores the multiple effects of active distribution network technologies on the economic benefits of distribution companies in all aspects and provides the theoretical basis of economic evaluation of distribution network.
