Small hydropower station and triple co-generation cooperative control system and control method for active distribution network

Abstract

The invention discloses a small hydropower station and triple co-generation cooperative control system and control method for an active distribution network. The small hydropower station and triple co-generation cooperative control system comprises a triple co-generation control system, wherein a HMU (small hydropower station control and management unit) is arranged at the small hydropower station assess part in the active distribution network; a CMU (triple co-generation control and management unit) is arranged at the triple co-generation control system assess part; a CC (small hydropower station and triple co-generation cooperative interactive controller) is arranged in a power distribution network in the area in which the small hydropower station and triple co-generation exist; the HMU, the CMU and the CC are connected through adopting a GOOSE communication network. According to the small hydropower station and triple co-generation cooperative control system and control method for the active distribution network, the problem that in the prior art, the absorption capacity of the power distribution network and the economic efficiency of the whole operation cannot be effectively improved due to the situation that the coordination control of the small hydropower station and combined cooling heating and power system is controlled and managed through adopting a system formed in a microgrid form is solved.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a coordinated control system and control method for small hydropower and triple power supply in an active distribution network. Background technique [0002] With the continuous access of new distributed energy resources (DER) to the distribution network and the development of smart grids, the characteristics of the original distribution network have been changed, and two-way power flow appears in the distribution network, which reduces the stability of the power grid. However, the original distribution network scheduling management mechanism and automation level have seriously restricted the optimal operation of small traditional power sources (such as small hydropower and thermal power) and distributed power sources. In response to this situation, the Active Distribution Network (ADN) technology has emerged as the times require, and has become a deve...
