In hydrometeorology area, the end of SMAP calibration model project for the lower Parnaíba river basins and Tiete, Paraná and Iguaçu rivers is emphasizes, as well as the beginning of similar project for the basins of the rivers Uruguay, São Francisco and Tocantins.

Also noteworthy is the continuity of project performance evaluation of other precipitation forecast models together or to replace the current model (ETA40), with a view to improve the quality of forecasts of flow rates next operative week.

Also in hydrometeorology area, it was implemented the first version of Flow Forecasting Management System (SGPV), which deals with the acquisition of data from agents. SGPV is being developed to minimize the associated risks with streamflow forecasting process for the PMO, which has become more complex and vulnerable due to methodological diversity of the models used which, in addition to hinder the management of individual processes, involves the use a large number of data files.

Within the Permanent Commission for Computing Methodologies and Analysis of Electric Sector Program (CPAMP / MME), began the partition of the equivalent subsystems for analysis used in the medium-term studies with NEWAVE model in more than an equivalent energy reservoir. This will give better representation for the hydrological diversity between the watersheds of the BIPS in the medium-term studies.

The load forecasts for the period of the 2014 Soccer World Cup were the subject of specific studies to meet the demand of electricity, both for reinforcement work to be performed in advance, and during the event. The Confederations Cup, held a year earlier, was a major FIFA event test and also to ONS, with the establishment of specific procedures for the event. There was a need to give greater attention to the expected changes in the demand around theBIPS, to adequately meet the cities and regions where this approach would be influenced by: changes in market behavior, change the school calendar and the usual working hours. During the World Cup matches in 2014, marked by the large flow of people, professionals related to sports and tourists, these changes occurred in the behavior of consumers served by distributors, especially in cities that hosted the event.

Besides the forecasting, in each half hour, of load curves for the BIPS Electro Process Programming,a detailed. Munite by minute forecastwas done in the period when change was expected in load behavior during games, to anticipate the expected sharp fluctuations in demand, characterized by large ramps down and freight rise in earlier and later times to competitions.

The high growth of the amount of wind power, 2,400 MW at the end of 2013 to 14,200 MW expected by the end of 2018, significantly increased the complexity that involves the data preparation activities, modeling and simulation of this generation studies and electrical analysis. This generation has come to represent a significant portion that can change not only the distribution of flows and voltage control, but also the dynamics of the BIPS. Therefore, it was necessary to make an effective data management for all of the wind, current and future parks.

This activity has enabled not only the most real representation of wind plants in simulation studies, but also obtained more accurate results and faithful in the analyzes in normal and dynamic regime. To perform the simulations, ONS had the support of CEPEL, which implemented the necessary adjustments in both ANAREDE programs, and in ANATEM.

In the use of DC systems simulator, various activities were performed throughout 2014, highlighting the following:

• First stage of the HVDC controllers replicas of the second dipole (Alstom)commissioning, covering the installation and commissioning of the supervisory system in field version and configuration of Alstom replicas for connection to the Master Control (ABB);
• Execution of corresponding routines to factory testing, acceptance and evaluation of dynamic performance, included in the commissioning of the HVDC controllers replicas of the second dipole in isolated operation;
• Preparation of the simulator to carry out the joint operation studies of ABB and Alstom controllers, contemplating the integration of RSCAD-RTDS models of both manufacturers in a single project;
• Implementation of dynamic performance studies the set of the first and second bipolos for the testing of the joint operation of ABB and Alstom controllers, under simplified network configuration;
• Execution of simulations for the evaluation of proposals of ONS to change the logic C&P of ABB controllers, in order to release of BPC operation mode after the occurrence of analysis in the field.
