Optimal interconnecting wind generation into Polish power system

The main objective of a Transmission System Operator is to operate the system in a safe, secure and efficient manner. Hence, the transmission lines and transformers should not be overloaded after interconnecting wind farms into transmission network. Wind generation results in decreasing conventional generation. On the other hand, the technical minimum of a thermal unit in power stations must not be violated. Such a task can be formulated as the minimization of a linear goal function subjected to linear equality (generation and demand balance) and inequality constraints (permissible branch flows and thermal generation minimum). The idea of a paper is to formulate and solve the problem as a linear programming task. Then the Matlab Optimization Tools is used to solve the linear optimization task. The mathematical background and the small example power system are presented in the paper.
