The network reliability is one of significant characteristics of operation of the power system that plays an important role in designing a standard electricity market especially in case of unit commitment. In the present article, a power network with maximum load 2700 MW is considered. For calculation of produced energy of each power plant and cost of production for 1 year, this network is examined in two modes with and without considering emergency exit of production units. Regarding the characteristics of production units like number, capacity and cost of production with zero probability of emergency exit for each of them and considering network peak load that is determined by the user. For computation cost of production of each power plant in the network and calculation of its cost of production, a graphical program is provided by Graphical User Interface (GUI) environment and MATLAB software, which computes the energy and costs of production of the system as well as rate of reliability indexes LOLP and EENS. According to such results, it can be concluded that the charged cost to the system for mode A that all production costs are entered the circuit without considering probability of their emergency exit (FOR = 0) and only based on their own production cost (or their biding prices in the market of electricity) will be much lesser than mode B, which units participate in supplying network load in the electricity market on the basis of their probability of presence (FOR 0).
Key words: Different constraints, graphical user interface, MATLAB, powerhouse, , ,
