Produtores de Água na Microbacia do Manancial Córrego do Veado – Presidente Venceslau, São Paulo: potencialidades em questão

The programs Water Producer and Water Mine are the starting point for the research, whose the main objective is to develop a study on the necessity and possibility to forming water producers in the Veado Creek Watershed Deer, located in Presidente Venceslau - Sao Paulo, in order to improve the quality and quantity of water from the spring. To this end, the implementation of programs in the spring, especially the Water Mine, developed by the State of Sao Paulo, could help change the situation in which degradation is the area of the watershed. The main methodological procedures were performed: survey and literature review, interviews with employees SEAAMA, CATI, interview with the president of the Association of Owners of Rural Watershed of Deer Creek; interview with landowners of the Fountain Creek Watershed Deer; work in the search field at the landfill to the DAE and the Association of Collectors of Recycled. We are dealing with issues such as the importance of the Code of forests with regard to the protection of water resources, decentralized management and participatory of water resources, Payment by Environmental Services, production of water, characterization and diagnosis of the environmental Microbacia of Wealth Córrego do Veado, sanitation of the municipality of Presidente Venceslau. Analyzed the current situation of the watershed of the spring, highlighting the main actions that have been performed by the municipality through the watershed program of the State of São Paulo City Hall and through the resources FEHIDRO. The obtained results allowed to demonstrate the need and the possibility of setting up the Project Mine Of Water in the watershed of the fountain and the interest of owners interviewed by adherence to the Project and the protection of the source

Decentralized AC power flow for real-time multi-TSO power system operation

This paper adjusts decentralized OPF optimization to the AC power flow problem in power systems with interconnected areas operated by diferent transmission system operators (TSO). The proposed methodology allows finding the operation point of a particular area without explicit knowledge of network data of the other interconnected areas, being only necessary to exchange border information related to the tie-lines between areas. The methodology is based on the decomposition of the first-order optimality conditions of the AC power flow, which is formulated as a nonlinear programming problem. To allow better visualization of the concept of independent operation of each TSO, an artificial neural network have been used for computing border information of the interconnected TSOs. A multi-area Power Flow tool can be seen as a basic building block able to address a large number of problems under a multi-TSO competitive market philosophy. The IEEE RTS-96 power system is used in order to show the operation and effectiveness of the decentralized AC Power Flow. ©2010 IEEE.
