Probabilistic Operation of Electric Power Systems Considering Environmental Constraint (Part 14)* -System Reliability and Economy-

摘要

When economical operation is considered as the operating cost or the fuel cost of each thermal station, then the economic operation tends to have a lower probability power supply because reduction of the power supply decreases the fuel cost. The practical economy of power system operation is considered in this paper by using not only the operating cost but also the income received for the supply of electricity. The optimum operation is scheduled so that it can satisfy the emission constraint and the probability of power supply becomes maximum. Using a model power system, each optimum operation is estimated considering the emission constraint. Results of simulation are reported and investigated.
