Recently the interest in renewable energy has been increased worldwide. Therefore, the microgrid is considered more efficient and flexibility to improve the economic and environmental conditions by integrating the traditional distributed energy resources using technology devices and information technology (IT). Blockchain is one of these technologies, which has attracted in microgrid applications to build a sustainable society. The blockchain concept can provides immutability of the transactions in the microgrid such as record the amount of power generation and verify the transaction between the generators and end-users. blockchain based smart contract can be used for audit or solving a transaction dispute between the producers and the users by strip the necessity to link with third parties. In this paper, we present a number of recent research works related with blockchain application in microgrid and the application of the blockchain to improve the transactive resilience in the microgrid using smart contract.

This paper presents the development of multiple-input single-output converter (MISO) with uneven load sharing controller. The premise of this study is to create uneven load current sharing between the converters at different loading conditions in order to maximize the efficiency of the overall MISO converter. The goal is to find a proper ratio of current from each converter to the total load current to achieve the greatest efficiency. The design and operation of the converter was tested and verified through simulation and hardware implementation. Different ratios of current from each converter were used to fully test the MISO converter. For the 5A and 6A load current, the maximum efficiencies were reached with the 70%/30% ratio case, with efficiencies of 94.91% and 95.07%, respectively. For 7A load current, the maximum efficiency was reached with the 60%/40% ratio case, with an efficiency of 94.59%. Results also demonstrate that the efficiency of the unequal current sharing outperforms that obtained from the equal current sharing method.

The photovoltaic (PV) emulator (PVE) is a specialized power supply that generates the same output as the PV module. However, the conventional control strategy called the direct referencing method (DRM) used for the PVE has oscillation problem. The problem is caused by the dependency of the DRM on the external components to compute the operating point. This problem can be overcome if the operating point is computed internally. This paper proposed a control strategy that compute the operating point internally using the particle swarm optimization (PSO). The resistance comparison method is chosen to implement the PSO into the PVE. The proposed PVE is compared with the conventional PVE that uses the DRM control strategy. Both PVEs use the similar buck converter, proportional-integral controller, and single diode model for a fair comparison. The result shows that the proposed PVE has no lower oscillation and higher accuracy when compared to the conventional PVE.

The growing need for highly reliable and efficient power supply of renewable energy resources and new sizeable loads necessitated novel ways to transfer electric power between them. In the current configuration, transformers are passive devices that do not enable dc systems to connect of interface the electric grid with other energy grids. With the growth of power devices and power electronic converters, direct current transmission and distribution systems using medium or high voltage provide power flow control between various energy networks. This talk would highlight power electronics technologies for the highly reliable dc transmission and distribution systems. Various configurations of solid-state transformer (SST) would be introduced especially modular multi-cell power converters among the configurations. Special focuses are paid on two different modulation strategies for reducing power losses and providing tolerant ability of switching device failures in modular multilevel converters. 2019 IEEE Conference on Energy Conversion (CENCON) 8 S1-1: Power Quality Room: Ball Room Karaton Time: 13:00 14:00 13:00 The 9-150 kHz Disturbance Characteristics of a Grid-connected Rooftop Photovoltaic System Gusdhi Rhazhya Ramadhan and Budi Sudiarto (Universitas Indonesia, Indonesia) Abstract: The usage of renewable energy is increasing in many countries, Indonesia included. This spike of interest is supported by its environmental-friendly nature and the fact that it is one of the most effective ways to combat global warming. Solar power plants are electricity generators with the ability to convert solar energy to electricity by using solar panels.However, solar power plants are indubitably dependent on solar energy, which can cause a fluctuation of output because solar energy is affected by weather and the cloud's condition.Generally, solar power plants have a power electronics component called an inverter. Inverters are used to convert the output of solar panels, the direct current (DC), to alternating current (AC). The usage of power electronics such as inverters plus the fluctuation of the solar panel commonly cause disturbances .Inverters usually have a switching rate higher than 1 kHz, which can cause disturbance in the range of 9-150 kHz throughout the whole system.However, there is little to none standardization regarding how much emission it is allowed to radiate at the 9-150Khz. With the aforementioned concerns in mind, this writing discusses research regarding the characteristics of disturbance on the 9-150Khz frequency on the On-Grid solar power plants located at SPBU Kuningan .Measurement is done on the output side of the solar inverter.

The peer-to-peer (P2P) energy trading creates a platform for all microgrid users to exchange their energy surplus and demand without the presence of a centralized authority. With P2P, the dynamic electricity market between nodes will be developed, thus increasing the overall throughput of the microgrid. To ensure the energy transactions in local energy trading meet the highest level of integrity, the blockchain system is implemented. Appropriate classification and structuring the literature on viable designs for local energy trading can assist researchers in effectively developing their subsequent planning for the local energy market. This study reviews the current research related to market clearing methods for blockchain-based P2P energy trading for microgrid system. The focus is on the auction theory, constrained optimization, game theory and agent methods.

Technology advancement is currently rising at a rapid rate. This increases the demands for digital electronics industry in Malaysia. However, there is one issue when it comes to electronics, it is susceptible to power disturbance. Power disturbance can be categorized into six types which are transients, interruptions, undervoltage, overvoltage, waveform distortion and voltage fluctuations. In this study, an uninterruptible power supply (UPS) using double-conversion technique is presented due to its ability to provide adequate power conditioning and backup power in power disturbance situation. The simulation and designing of the converters such as rectifier, boost converter and inverter are presented using the MATLAB/Simulink. The simulation results showed that the UPS system was able to provide a continuous power supply with acceptable THD levels.

This paper proposes a new quasi-Z-source (QZS) four-switch three-phase inverter (FSTPI) where one load phase is connected to the split DC-link capacitor of the input voltage. Compared to the conventional QZS-FSTP topology, the proposed topology eliminates the LC component's instability in the QZS network thus making it suitable for a fault-tolerant control system. Furthermore, the proposed topology does not require any additional active switches. The switching modulation technique is designed to control the proposed topology where a DC-link voltage compensation is introduced in the modulation algorithm. This technique minimizes the output voltage imbalance by sensing the split DC-link voltage error and adjusting the switching algorithm accordingly. The dynamic performance of the proposed topology is evaluated in MATLAB/Simulink environment. It is shown that by using the proposed topology; there is an improvement on the line-to-line output voltage, and reduction in the total harmonic distortion of the line-to-line voltage compared to the previous topology. The proposed topology also produces a similar boost factor as the conventional QZS based on the six-switch three-phase inverter (SSTPI). The theoretical analysis based on the proposed topology are also in line with the simulation results.

This research addresses two finite control set-model predictive control (FCS-MPC) methods employed on the switched-battery boost-multilevel inverter (SBBMLI). The simulation analysis begins with the generalized formulation and follows with the Euler method of the FCS-MPC. The performance of the generalized formulation is considered at the capacitor connected in parallel with the load. Meanwhile, the Euler method is considered at the actual load of different configurations. A simulation analysis of a switched-battery boost-multilevel inverter (SBBMLI) is therefore designed and analyzed to demonstrate the efficacy of the proposed approach. The FCS-MPC control module with the two methods is implemented to confirm the performance of their operation using Matlab Simulink simulation. For the stated case study, a 0.21% to 1.25% increment of THD in the generalized SBBMLI problem formulation compared with the FCS-MPC using the Euler method and the tracking problem is an acceptable limit for the FCS-MPC performance deterioration.

This paper presents a refined finite-state predictive torque control (FS-PTC) for two-level Voltage Source Inverter (2L-VSI) of induction motor (IM) by introducing a specific voltage vector selection lookup table to the algorithm. The concept behind this method is to decrease the number of voltage vectors (VVs) instead of using seven voltage vectors (VVs) to test the cost function, resulting in a substantial reduction in the algorithm's analytical terms. MATLAB/ Simulink is used to analyze the efficiency of the refined algorithm under torque dynamic condition (staircase speed reference). The results of the simulations indicate that the refined algorithms able to regulate torque performance but not the stator flux performance or the total harmonic distortion (THD) stator current. Nevertheless, by increasing the weighting factor, it could reduce the flux ripple and decrease the THD current.
