Normal random number generator

Description:
This device produce periodically a number randomly with a normal law. To generate it, it uses the Box-Muller methods. To generate the necessary uniform distributions, it uses the park and Miller metho... see mored.

seed: The seed represents the seed of the generator. A same seed will produce the same set of number.

Ts: At each time step of Ts, the random number generator will compute another random number.

variance: The variance represents the law variance.

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.
