In this work we present some practical guidelines for applying set-oriented methods for the solution of multi-objective optimization problems to highdimensional real world problems. First we briefly review the main concepts of multi-objective optimization and describe how these problems are related to selfoptimizing systems. In addition we give an overview on the basic set-oriented methods. Finally we apply a new variant of these methods to the energy management for an onboard storage system of a tram, where the aim is to reduce both overhead line peak power and energy consumption simultaneously.

“…For a detailed description of this application see [8]. Since the drive cycle of the tram is divided into 1241 track sections and the energy management system has to assign a reference value to each of these sections, we have to solve a MOP with 2 objective functions and 1241 parameters.…”

“…En [19] se propone un control PI de tensión, el cual determina la consigna de corriente para controlar la velocidad de una máquina de inducción, la cual tiene acoplado al rotor un volante de inercia, los resultados de simulación y experimentales muestran una reducción no mayor al 2% durante la aceleración y desaceleración del tren. En [20], la compensación de voltaje del bus de CD se realiza midiendo la diferencia entre la potencia nominal y la potencia instantánea del bus, a partir de esta diferencia se define el modo de operación (carga/descarga) de un banco de ultracapacitores. En el trabajo [21], se han presentado resultados en simulación y experimentales, en donde se muestran compensaciones de 16% y 20% ante variaciones de tensión (baja y sobretensión) del bus de CD, esto a través del control indirecto de la corriente de línea y la corriente requerida por el tren.…”

One of the main problems in electric power network in metropolitan train transportation occurs when a train accelerates and decelerates, which can produce over and under voltage of DC link power supply and an important amount of energy is transferred from and into the DC link. The above mentioned affects the AC rectifier substations power system, producing interruptions of the traffic trains. This paper proposes an analysis by modeling and simulation of a train in order to evaluate the behavior of the DC link voltage supply applied to six stations. The storage kinetic energy of the metropolitan rail trains during accelerations is normally burned in order to avoid DC link perturbation voltage. However this energy can be recovered and used to compensate the DC link voltage variations, which can help to save an important amount of energy and improve the overall performance of the system. So, in this paper is proposed a Voltage Compensation System (VCS) throughout an energy storage system. Finally, an evaluation of the saved energy and a better performance operation of the metropolitan railways can be demonstrated with the results obtained.

“…Efficient ways of overcoming these problems are removing the overhead cables (catenary-less zones) and implementing onboard ESS as Supercapacitor (SC) [2][3] [4], Batteries (BT) [5] or hybrid ESS combining BT and SC [3] [6][7] to supply energy during the travel (partially or entirely).…”

In this paper an optimal operation mode control for a tramway with a hybrid energy storage system (battery+supercapacitor) is presented. The optimization process to obtain the setpoints for the control strategy is done by mean of multi-objective genetic algorithm (GA). The objective fitness functions are based on a cost model considering: the energy absorbed from the catenary, the battery+supercapacitor cycling cost and the cost of the lost energy in the crowbar. The aim of the proposed approach is to minimize the daily operating cost of the tramway taking into account the degradation of the energy storage systems and fulfilling the performance of the tramway in the catenary-less zone. Furthermore, a sizing analysis is done by comparing the proposed solution with a base scenario (supercapacitor based) to evaluate the impact on the daily operating cost under several unscheduled-stop events during the trip.
