Abstract

Neighboring networks need to be interconnected for many reasons, such as the benefits of power sales in either direction across the boundaries, which take the advantages of differential power demand according to time of day or seasonal/weather changes. Sharing resources in this way would defer installation of new generation; it would also involve sharing the provision of spinning reserve and reduce the hot standby reserve requirements.
In any interconnected power systems, the most important problem facing the power system operators is the management of their own power system transactions (purchasing or selling the electric power) to achieve maximum benefits from interconnection. Some computer programs have been produced to deal with this problem such as Multi-Areas Production Simulation Program (MAPS) package. The operators have to run four dependent programs to make a decision to sell or purchase electric energy, which may take a long time and may cause accumulated errors
The main object of the thesis is to create an efficient and simple tool to help the interconnected power systems operators to supply certain load at minimum cost and to sell the surplus electric energy at maximum benefits through the interconnection systems and under power market constraints.
As a result, a new computer program was developed by using Borland C++ language. The program deals directly with the mentioned problem and helps the interconnected power system’s operators to take reliable decisions simply. The program also, determines the units’ commitment, and develops the generating units’ priority list.
The proposed computer program is employed for managing the interconnection system between the Egyptian Unified Power System and the Arabic neighboring power systems from year 1999 to year 2006. To complete this calculation a peak load forecasting is performed for yearly peak load and normal working day load for a summer and a winter day.
A general study of power marketing included spot market pricing, models and problems of power markets and constraints of pace change to a competitive market are obtained. It also gives main dominant shapes of power sector reform such as demand side management, transmission congestion management and ancillary services procurement. Some approaches of power sector regulation are presented. The current and future statuses of electricity market in Egypt are proposed.
