Chapter 9 - Reliability-Based Scheduling of Active Distribution System With the Integration of Wind Power Generation

Abstract

This chapter proposes a daily operation of active distribution network with integration of wind power generation (WPG). The authors consider reliability assessment in this study, which is one of the key indices to measure the impact of the renewable units’ outage such as WPG. Active distribution systems active management (AM) technologies are applied so that the distribution network components can be controlled in real time condition based on the real time measurements of voltage and current at the network. The proposed framework maximizes the distribution network operator (DNO) benefits in short-term scheduling model. In the proposed model, DNO has been considered the battery charging/discharging decisions, on load tap changer of substation transformer and control of reactive power compensators as three options of AM. A Markov model is proposed to a comprehensive reliability assessment of WPG and battery storage system (BSS). A Markov model provides the characteristics of the major components of the WPG and BSS as well as their influences on the reliability of a distribution network. Scenario-based approach is used to model the uncertainties of WPG and load value. The proposed model is successfully applied to the 9-bus test system in order to evaluate the performance of the model. The results compare active distribution network and passive distribution network.
