The combined economic-environmental dispatch problem is multidimensional, non-linear and highly constrained problem. A new model for multi-objective optimization of the combined economic-environmental power dispatch problem was developed, which focuses to cost and emissions criteria. A new computer code was developed based on improved genetic algorithm which is a powerful optimization method. It was tested on real systems. Results show that the optimal solution for real systems leads to decrease of quantity of undesired emissions to the environment and to decrease of generation costs.

In the paper, the use of electric vehicle public charging stations with energy storage system as a solution for voltage regulation in low-voltage grids with photovoltaics is introduced. A novel method is proposed to determine the energy storage system charging load, required for voltage regulation and compare the results for the different locations on the feeder. With time-series simulations, the energy size required for a station energy storage system is quantified. A Belgian low-voltage residential grid is used as a case study. The method and simulation results show the effectiveness of using public electric vehicle charging facilities with the additional function of voltage regulation in feeders with photovoltaics.

A new model for optimal generation scheduling of power system considering generation units availability is developed. The model is based on minimisation of costs, minimisation of emissions and maximal availability of generation units. The model is developed for application to real power systems and includes consideration about water quantities for hydro power plants. A computer code was developed which enables optimisation of real systems. The results give several solutions, because the improvement of one criterion does not necessarily leads to the improvement of the other two and the decision on the best compromise solution has to be made.
