“Predictive Control – the Powerful Method to Control Power Converters and Drives in the Future”

Up to the present the control of electrical power using power converters has been based on the principle of mean value, using pulse width modulation with linear controllers in a cascaded structure.

Recent research works have demonstrated that it is possible to use Predictive Control to control electrical energy with the use of power converters, without using modulators and linear controllers. This is a new approach that will have a strong impact on control in power electronics in coming decades.

The main advantages of predictive control are:

  • Concepts are very intuitive and easy to understand.
  • It can be applied to a great variety of systems.
  • The multivariable case can be easily considered.
  • Dead times can be compensated.
  • Easy inclusion of non-linearities in the model.
  • Simple treatment of constraints.
  • The resulting controller is easy to implement.
  • This methodology is open to include modifications and extensions depending on specific applications.

The participants of this tutorial will learn:

  • The basic concepts and ideas.
  • Different types of predictive controllers.
  • Detailed examples of predictive controllers.

Summary of Keynote

“Incentive Regulation in the Distribution Industry”

Electrical distribution companies, being network industries, transport and distribute electric power from connection points of the transmission system to end consumers for industrial and residential usage at appropriate voltage levels. This activity is organized in public service utilities that buy power supply from generators.

A growing challenge in the restructuring of the electrical sector, where competition is introduced in the generation area, is to achieve equivalent efficiencies in the electrical distribution service, an activity that develops in a monopolistic environment.

To regulate electrical distribution, most Latin-American countries that have implemented this transformation have adopted a “benchmark” scheme, using the concept of an efficient company which is a company that is adapted to demand and that operates under an optimal investment and operations plan. Under this scheme, to force companies to be efficient, the regulator fixes prices according to the costs of an efficient company (Capex, Opex, losses and non-supplied energy), designed from square one and without considering actual companies. The real company will get a normal profitability only if it is capable of emulating the efficient company, reducing its operating and investment expenditure, thus minimizing the present value of its costs. In general, this regulation, which introduces a virtual competition, has implied a reduction trend in distribution tariffs, obtained through a regulated periodic process.

The keynote will describe the benchmark regulation in Latin America power distribution, evaluate the results, and assess what can be learned from that experience, and the challenges that may arise in the future, particularly with the arrival of distributed generation.
