“…Among the most critical applications of UCs can point to controlled electric drives [15,16], RTG cranes and elevators for braking energy [17][18][19][20][21], renewable energy (full cell [22], photovoltaic system [23] and wind turbine [24] contributions), diesel-electric generators include gantry cranes [25][26][27] and hybrid excavator machines [28], power quality, uninterruptible power supplies, and traction drives (rail, road, and off-road vehicles) [29][30][31][32]. Figure 8 shows the overall scheme of the dual hoist STS crane which is connected to the POLB grid through the AC/DC/AC converters to avoid the voltage rise, leading power factor, and harmonic distortions [33].…”

The use of energy storage with high power density and fast response time at container terminals (CTs) with a power demand of tens of megawatts is one of the most critical factors for peak reduction and economic benefits. Peak shaving can balance the load demand and facilitate the participation of small power units in generation based on renewable energies. Therefore, in this paper, the economic efficiency of peak demand reduction in ship to shore (STS) cranes based on the ultracapacitor (UC) energy storage sizing has been investigated. The results show the UC energy storage significantly reduce the peak demand, increasing the load factor, load leveling, and most importantly, an outstanding reduction in power and energy cost. In fact, the suggested approach is the start point to improve reliability and reduce peak demand energy consumption.

“…To absorb the excess energy produced during the lowering of the container, an energy storage system can be attached to the DC bus, whose energy can then be used to help lift the next container. In the literature, the ESS solution in RTG cranes is mainly focused and used to save energy on a single RTG system [5,8]. The electrical grid is a hierarchal network of synchronised and interconnected power supplies and consumers distributed over a wide geographic area.…”

“…The literature introducing the potential impact of using energy storage systems (ESS) to support the diesel and electric RTG cranes is beginning to appear [6][7][8][9][10][11]. For example, Flynn et al [10] developed a hybrid energy source model for an RTG crane including a flywheel energy store.…”

The global consumerism trend and the increase in worldwide population is increasing the need to improve the efficiency of marine container transportation. The high operating costs, pollution and noise of the diesel yard equipment is leading sea ports to move towards replacing diesel RTG cranes with electric Rubber Tyre Gantry (RTG) cranes which offer reduced environmental impact and higher energy efficiency. However, ports will require smarter solutions to meet the increased demand on the electrical distribution network due to the electrification of RTGs. This paper aims to highlight the peak demand problem in the two electrical cranes network and attempts to increase the energy saving at ports by using two different technologies: Energy Storage System (ESS) and Active Front End (AFE). This article introduces one of the first extensive investigations into different networks of RTG crane models and compares the benefits of using either AFE or ESS. The proposed RTG crane models and network parameters are validated using data collected at the Port of Felixstowe, UK. The results of the proposed RTG cranes network show a significant peak demand reduction and energy cost saving.

“…Once the global HESS reference current is calculated, the Hybrid Logic block distributes this current between the battery and the supercapacitor. In this paper, the most used sharing control strategy for parallel active hybrid topologies [ 31 ] has been selected: since the goal is that the battery covers the average active power set-point, delivering the peaks and power fluctuations to the supercapacitor, a first order Low Past Filter (LPF) with time constant τ is employed [ 32 , 33 , 34 , 35 , 36 ]. This simple sharing strategy guarantees that the dynamic stress and losses of the battery are reduced, increasing its lifetime.…”

The future of the grid includes distributed generation and smart grid technologies. Demand Side Management (DSM) systems will also be essential to achieve a high level of reliability and robustness in power systems. To do that, expanding the Advanced Metering Infrastructure (AMI) and Energy Management Systems (EMS) are necessary. The trend direction is towards the creation of energy resource hubs, such as the smart community concept. This paper presents a smart multiconverter system for residential/housing sector with a Hybrid Energy Storage System (HESS) consisting of supercapacitor and battery, and with local photovoltaic (PV) energy source integration. The device works as a distributed energy unit located in each house of the community, receiving active power set-points provided by a smart community EMS. This central EMS is responsible for managing the active energy flows between the electricity grid, renewable energy sources, storage equipment and loads existing in the community. The proposed multiconverter is responsible for complying with the reference active power set-points with proper power quality; guaranteeing that the local PV modules operate with a Maximum Power Point Tracking (MPPT) algorithm; and extending the lifetime of the battery thanks to a cooperative operation of the HESS. A simulation model has been developed in order to show the detailed operation of the system. Finally, a prototype of the multiconverter platform has been implemented and some experimental tests have been carried out to validate it.
