Complex optimisation of the control of interconnected power systems at the interstate level is related to solution and correction of multi-level hierarchical problems of dynamic programming in general, its separate subproblems differing in the time-space and situation aspects. Starting from the complex control of instantaneous steady-states (ESS), general principles of mathematical methods and tools, applied for solution of the multi-stage hierarchical dynamic programming problem, are considered.

The paper presents a short description of research results of the Baltic Association of System Research in Energy (BASRE) considering international collaboration and their application in development of the theory and methods of complex optimisation of the control of operation and reliability of Interconnected Power Systems (IPS) with respective net of coordinating dispatch centers. The centers operate at the interstate and regional level in freemarket conditions. The game theory applied considers the possibilities of providing optimal reliability of operation in the case of large disturbances. The theory and methods are applied to the control of IPS of Baltic States in the interstate control center DC Baltija which is unique in the whole world.
