“…So, we consider 400KW because this time BESS will discharge to meet the demand and the operation period of BESS is around 2 hours &15minutes. The details of UTP Microgrid can be found in [16]. In Figure 1, the load profile of UTP has been demonstrated.…”

Photovoltaic (PV) and Battery Energy Storage System (BESS) are becoming more popular in global energy landscape. Some excellent characteristics such as versatility, expansion performance, fleet response time and modularity, make BESS more effective device.By considering Isolated Microgrid (IMG) system, PV-BESS hybrid system can be used for peak load shaving application. Here, chargedischarge operation of BESS and optimal usage of PV is the most important requirement. Previously few techniques have been proposed for shaving the peak load and they controlled the charge-discharge operation of battery. However, the techniques contain some limitations. It cannot ensure the optimal usage of PV and the charge-discharge controlling techniques are not well fitted for IMG system. In this work, we have proposed a Modified Decision Tree Algorithm to achieve peak load shaving service. The proposed algorithm can control the charge-discharge operation of BESS and ensure the optimal usage of PV generation unit. The proposed method has been applied on the load profile of UniversitiTeknologi PETRONAS (UTP). The results demonstrate that, the proposed algorithm can minimize the demand of UTP. A comparative analysis has been done between the proposed algorithm and the latest peak shaving decision tree algorithm. The comparative analysis reflects that the proposed algorithm can ensure the optimal usage of PV unit and can minimize the demand by few hours more than the latest algorithm. The proposed algorithm has also considered the optimal generation dispatch which can save more energy, reduce fuel consumption, and carbon emission. This method is more environment friendly and economically benefited.

“…A low load factor signifies that an electricity system is being operated inefficiently and is economically poor [100]. Thus, a high load factor is desirable in order to ensure that the seaport microgrid is economically viable by utilizing the total plant capacity for the longest possible period [101]. As a result, the overall cost of providing electric energy will be reduced.…”

A Review of the Conceptualization and Operational Management of Seaport Microgrids on the Shore and Seaside

Seaports are well known as the medium that has evolved into the central link between sea and land for complex marine activities. The growth in maritime logistics particularly necessitates a large volume of energy supply in order to maintain the operation of sea trade, resulting in an imbalance between generation and demand sides. Future projections for three major concerns show an increase in load demand, cost of operation, and environmental issues. In order to overcome these problems, integrating microgrids as an innovative technology in the seaport power system appears to be a vital strategy. It is believed that microgrids enhance seaport operation by providing sustainable, environmentally friendly, and cost-effective energy. Although microgrids are well established and widely used in a variety of operations on land, their incorporation into the seaport is still limited. The involvement of a variety of heavy loads such as all-electric ships, cranes, cold ironing, and buildings infrastructure renders it a complicated arrangement task in several aspects, which necessitates further research and leaves space for improvement. In this paper, an overview of the seaport microgrids in terms of their concepts and operation management is presented. It provides the perspectives for integrating the microgrid concept into a seaport from both shore side and seaside as a smart initiative for the green port’s vision. Future research directions are discussed towards the development of a more efficient marine power system.

Test-Rig Simulation on Hybrid Thermal Barrier Coating Assisted with Cooling Air System for Advanced Gas Turbine under Prolonged Exposures—A Review

et al. 2021

Thermal barrier coating (TBC) and cooling air systems are among the technologies that have been introduced and applied in pursuing the extensive development of advanced gas turbine. TBC is used to protect the gas turbine components from the higher operating temperature of advanced gas turbine, whereas cooling air systems are applied to assist TBC in lowering the temperature exposure of protected surfaces. Generally, a gas turbine operates in three main operational modes, which are base load, peak load, and part peak load. TBC performance under these three operational modes has become essential to be studied, as it will provide the gas turbine owners not only with the behaviors and damage mechanism of TBC but also a TBC life prediction in a particular operating condition. For TBC under base load or so called steady-state condition, a number of studies have been reviewed and discussed. However, it has been found that most of the studies have been conducted without the assistance of a cooling air system, which does not simulate the TBC in advanced gas turbine completely. From this review, the studies on TBC-assisted cooling air system to simulate the advanced gas turbine operating conditions have also been summarized, which are limited to test rig simulations under thermal cyclic mode where thermal cyclic represents peak and part peak load conditions. The equipment used to simulate the gas turbine operating condition, test temperatures, and durations are parameters that have been taken into consideration under this review. Finally, a test rig that is capable of simulating both TBC and cooling air effects at a high operating temperature of advanced gas turbines for prolonged exposure under steady-state condition has been proposed to be developed.
