Abstract—This paper proposes a new approach for solving the complicated environmental protection power dispatch (EPPD) problem for modern power system. In the work, pollutant emission and generation cost, which are two conflicting objective functions, are taken into account concurrently within the optimization process. Then, the proposed interactive bi-objective programming with valuable trade-off (IBPVT) approach is applied to obtain an pareto-optimal solution, which is an emission-cost trade-off solution, by following the intention of the decision maker. The salient feature of the proposed approach is that it can provide a flexible and compromising solution through an easy and interactive process to help power systems obtain the optimal emission-cost power dispatch. Two test cases have been demonstrated and proven to obtain the superior features. The encouraging simulation results show that the proposed approach is capable of obtaining high quality solutions for practical EPPD problems.
