Short-Term Scheduling of Active Distribution Systems
Description:
The latest distribution management systems tend to incorporate optimization functions for the short-term scheduling of the various energy and control resources available in the network (e.g., embedded... see more generators, reactive power compensators and transformers equipped with on-load tap changers). The short-term scheduling procedure adopted in the paper is composed by two stages: a day-ahead scheduler for the optimization of distributed resources production during the following day, an intra-day scheduler that every 15 minutes adjusts the scheduling in order to take into account the operation requirements and constraints of the distribution network. The intra-day scheduler solves a non-linear multi-objective optimization problem by iteratively applying a mixed-integer linear programming (MILP) algorithm. The linearization of the optimization function and the constraints is achieved by the use of sensitivity coefficients obtained from the results of a three phase power flow calculation. The paper shows the application of the proposed approach to a medium-voltage 120 buses network with 10 dispatchable generators and 2 transformers equipped with on-load tap changers.

A PROCEDURE FOR THE AUTOMATIC SCHEDULING OF DISTRIBUTED ENERGY RESOURCES IN MEDIUM VOLTAGE NETWORKS
Description:
The paper presents the main characteristics of a centralized two-stage scheduler designed for the integration in the Distribution Management System (DMS) under development in the framework of an Itali... see morean “Smart Grid” Project. The paper first reviews the trends in the automation of power distribution networks, and then describes the two-stage scheduler and its application to typical Italian urban and rural distribution feeders.
