Battery energy storage system makes seaport microgrids more reliable, flexible, and resilient. However, it is necessary to develop, test, and validate the functionality of battery energy storage controller in such a way that it balances power mismatch of demand and supply by charging and discharging the battery. This paper examines the performance of battery energy storage controller (BESC) to be employed in harbour grids in such a way that mismatch of power supply and load demand is compensated by charging and discharging the battery energy storage system. This controller can save energy efficiently and shave peak load demand in harbour grids where transmission and distribution systems have a limited power capacity. The controller of battery energy storage system is first developed offline in the MATLAB/Simulink, and then implemented with IEC61850 communication protocol for publishing and subscribing GOOSE messages. Moreover, to test the effectiveness of the proposed control algorithm of battery energy storage system, a real data from the local distribution system operator Vaasan Sähköverkko and harbour operator Kvarken port of Vaasa has been implemented. The simulation results show that the designed battery energy storage controller can balance power inside microgrid by charging and discharging of battery storage. The applied technique used in this paper is useful to validate the controller functionality in real time with the concept of simulation-in-loop (SIL), which is a practical approach, and it provides a cost-effective way to observe the performance of the controller.

This paper presents an experimental investigation into the operating characteristics of arc fault detection devices according to the tests in the Standard GB31143. A testing platform was set up in the laboratory, and the tripping time of AFDD samples was recorded. Some AFDDs cannot detect the arc fault in time. Identifying the fault arc current in the case of masking load is a tremendous challenge to AFDDs now. The algorithm in the AFDDs for cutting off the circuit within the specified time also needs to be further improved.

Photovoltaic power has become one of the most popular energy due to environmental factors. However, solar power generation has brought many challenges for power system operations. To optimize safety and reduce costs of power system operations, an accurate and reliable solar power forecasting model is significance. This study proposes a deep learning method to improve the performance of short-term solar power forecasting, which includes data preprocessing, feature engineering, Kernel Principal Component Analysis, Gated Recurrent Unit Network training mode based on time of the day classification, and post processing with error correction. Both historical solar power, solar irradiance, and Numerical Weather Prediction (NWP) data, such as temperature, irradiance, rainfall, wind speed, air pressure, humidity, are considered as input dataset in this work. As a case study, the measured solar power data from ten solar sites in Taiwan are forecasted for the next day PV power outputs with one-hour resolution. The error index such as Normalized Root Mean Squared Error (NRMSE), Normalized Mean Absolute Percent Error (NMAPE) are chosen to evaluate the performance of forecasting models. Compared with other benchmark models including ANN, LSTM, XGBoost, and single GRU, the experimental results by the proposed forecasting model show its high performance. Furthermore, the proposed model also demonstrates the importance of data preprocessing and post processing based on error correction.

Seaports are the key pivots of maritime transportation system and have great impacts on the overall system efficiency. Varying with the cargo types, seaports can be classified as different types, such as container seaports and bulk seaports. The bulk seaports are used to handle various liquid and solid cargos in large volumes, such as petroleum, liquefied natural gas (LNG) and coal. The liquid cargos are generally bunkering into the transmission pipeline system and the solid cargos are generally transferred by the belt conveyors. In this paper, the energy scheduling models for the bunkering system and the belt conveyor are proposed and then the overall energy-transport scheduling problem for bulk seaport is formulated. The test case verifies the validity of proposed method and the results show that the scheduling of transmission pipeline system and belt conveyor provide adequate flexibilities to the bulk seaport integrated energy system.

The fast-growing electric car market inevitably requires the construction of new infrastructures for recharging vehicles. The design of new parking lots should be done by analyzing the expected profiles and the type of environment considered, in order to take full advantage of the technology and choose the charging modes that best suit that context. This article analyzes the different electric vehicle charging modes, the regulations that govern them and the possible types of parking. Subsequently, it is proposed a model of control and regulation of power flows that, depending on the type of parking and the types of charging stations, can manage up to four recharges simultaneously, without oversizing the infrastructure. This model, called Sharing Model Control (SMC), offers charging options that customers can select through an app interface; allowing them to choose the type of charging and its cost according to their needs. The main advantage of SMC is to allow the management of the same number of customers with a smaller installation of charging infrastructure, with all the economic benefits that come with it.

In this paper, the issues related to short-circuit calculations in hybrid AC/DC microgrids are discussed. The reference standard for short-current calculations in DC systems is the IEC 61660, which provides a mathematical formulation of the problem. The standard only includes radial DC grids and does not consider a more complex system, such as meshed DC systems or a hybrid AC/DC microgrid. This paper proposes a generalized approach that can be used independently of the characteristics of the hybrid system. The proposed approach is applied to two test microgrids and the results are compared with those obtained simulating the same grids with Neplan 360.

Nowadays, the direct-sale of electricity by large users has become an important development trend. Combining the quota system, it can promote the consumption of renewable energy and achieve the goal of carbon neutrality. In order to make the direct transaction of electricity more transparent and reliable, relying on the blockchain technology with the characteristics of encryption and decentralization, a transaction platform for the direct transaction of electricity has been constructed. The first is that it involves blockchain smart contracts to realize the direct power purchase transaction management function and ensure the safety and trustworthiness of the power direct sale transaction path. Secondly, introduce the load peak shaving market, design peak shaving market transactions and green certificate matching transactions to participate in the direct selling market link, and compare the three transaction modes. Finally, run the constructed model on the designed blockchain trading platform to complete the entire process of energy trading. The results show that the participation of the green certificate mechanism and the peak shaving mechanism in the direct purchase market can rationally allocate market resources and guide emission reduction through market means, which is conducive to the further realization of carbon neutrality in electricity market transactions.

In energy consumption level, buildings are currently the largest sector, therefore, the energy efficiency of these structures, assumes a priority role in refurbishing projects. The “building automation” as well as the redesign of the electrical and thermal system of a structure can offer significant contributions in terms of energy saving, comfort and functionality. Recent policies introduced the nZEB (Nearly Zero-Energy Building) qualification. The challenge we are facing is to work on the refurbishment of existing buildings by identifying a model that on the one hand allows nzeb qualification and on the other hand is applicable to existing buildings with all the technical and economic constraints. In this article is presented a model appliable to old existing buildings with a case study of the refurbishment of an historical university department located in the hystoric center of Rome, through the use of software that can create dynamic models of operation faithful to the real case. The goal of the paper is to introduce a new model called Nearly Zero-Energy Refurbished Buildings (nZERBs).

The grounding grid plays a vital role in the safe and stable operation of an electrical system. To reduce the equipment damage and electric shock risks, an effective ground grid design for the system is necessary. In this paper, the PEEC method for the lossy ground is adopted to give a comprehensive analysis of the electric potential distribution around grounding grids under ground-fault conditions. The influence of the grounding structure, ground depth, and soil conductivity is discussed. The relationship between grounding grids structure and the step/transfer voltage are studied. This will benefit the grounding system design to guarantee electrical safety.

A frequency modulation (FM) radio signal receiver is an important device for radio transmitters. The FM radio signal receiver is mounted on the radio transmitter, and its circuit is connected to the electronic system inside the radio transmitter. Therefore, it is necessary to consider the electromagnetic interference (EMI) produced by the FM radio signal receiver to prevent damage caused by interference. This study investigated the EMI characteristics of an FM radio signal receiver in terms of conducted emissions and radiated emissions. The conducted emissions were measured in the frequency range of 150 kHz to 30 MHz and exceeded the CISPR22 standard at frequencies of 370 kHz (−2.4 dB) and 480 kHz (−6.5 dB). The radiated emissions were measured in the frequency range of 30 MHz to 1000 MHz and exceeded the EN55022 standard at a frequency of 33.93 MHz (−13 dB). The conducted emissions were reduced using an axial ferrite bead, while the radiated emissions were attenuated using multipoint grounding and shielding techniques. The axial ferrite beads could attenuate the conducted emissions by 8 dB. The multi-point grounding and shielding techniques attenuated the radiated emissions by approximately 22 dB. These EMI attenuation methods demonstrated satisfactory attenuation performance and resulted in the EMI satisfying the relevant standards.
