A multiple objective mixed integer linear programming model for power generatio...
Antunes, C. Henggeler; Martins, A. Gomes; Brito, Isabel SofiaPower generation expansion planning inherently involves multiple, conflicting and incommensurate objectives. Therefore, mathematical models become more realistic if distinct evaluation aspects, such as cost and environmental concerns, are explicitly considered as objective functions rather than being encompassed by a single economic indicator. With the aid of multiple objective models, decision makers may grasp...
On the use of reactive power as an endogenous variable in short-term load forec...
Santos, P. Jorge; Martins, A. Gomes; Pires, A. J.In the last decades, short-term load forecasting(STLF) has been the object of particular attention in the power systems field. STLF has been applied almost exclusively to the generation sector, based on variables, which are transversal to most models. Among the most significant variables we can find load, expressed as active power (MW), as well as exogenous variables, such as weather and economy-related ones; a...
Simulation-based assessment of electric load management programs
Gomes, A.; Martins, A. Gomes; Figueiredo, R.The paper describes a methodology for assessing the contribution of storage type loads to an electric energy system's load curve and for evaluating the impact of load shedding actions, as part of load management programs, on the system's load curve. The methodology uses physically based individual load models and an aggregation procedure that accounts for both statistical reference patterns of the energy servic...

Clímaco, João; Antunes, C. Henggeler; Martins, A. Gomes; Almeida, A. TraçaThe planning of new units for electrical power generation is a problem which involves different and conflicting aspects. Besides cost, security issues and environmental concerns must be explicitly incorporated into the models. In this way mathematical models become more realistic, and they enhance the decision maker's comprehension of the complex and conflicting nature of the distinct aspects of the problem. A ...
