For hybrid energy systems utilizing renewable energy sources such as the power grid of Phu Quy island - Binh Thuan province, the integration of battery energy storage system (BESS) could be seen as a practical solution with remarkable advantages including economic and technical preeminence. BESS contributes to increasing renewable energy penetration, enhancing system stability and reducing the dependence on fossil fuel generation. However, the integration of BESS into an existing hybrid power system also necessitates to conduct a quantitative analysis of the performance of different solutions. This study investigates operational data of Phu Quy power grid for one year, evaluates solar energy potential and proposes a proper BESS integration solution based on a careful quantitative analysis. The simulation results show that selection of larger BESS capacity increases penetration rate of renewable energy. Nevertheless, of all proposed BESS integrated scenarios, renewable energy penetration rate as well as diesel consumption do not show a major difference. Therefore, choosing BESS also needs to consider the load capacity and time required to start and interconnect standby diesel generators.

An efficiency of heat recovery steam generator (HRSG) plays an important role in the power productivity of combined cycle power plants. One of the essential systems in HRSG related to efficiency is high pressure (HP) economizer and high pressure (HP) evaporator. This paper presents a solution to overcome HRSG which has decreased energy performance output from low production high pressure steam flow system. The proposed method solves the problems associated with increasing the energy output performance of HRSG by increasing steam production. HP economizer and HP evaporator tube replacement solutions are based on the idea that high pressure steam system production is reduced due to low heat absorption due to blocking of gas flows from waste trapped between the fintubes that cannot be cleaned by water jet method, another thing is result of the assessment which the number of tubes below the minimum allowable wall thickness. The feasibility of this concept is assessed based on the calculation of the increase in steam production and energy output of HRSG using the thermodynamic concept. Steam production and energy output compared between at commissioning, before replacement tubes and after replacement tubes. The results presents that there is returned HP steam flow in HRSG output by 45.17 percent. The method proposed in this paper can be used for HRSG which has experienced decrease in performance at the high pressure system output flow due to low heat absorption, especially for horizontal dual pressure type HRSGs with an operating life of more than 20 years.

This paper proposes a new type of Nonsingular Terminal Sliding Mode Controller (NTSMC) for a variable speed Horizontal-Axis Wind Turbine (HAWT) with a direct drive Radial Flux Permanent Magnet Generator (RFPMG). In order to have more accuracy in the dynamic models, both HAWT and RFPMG are simulated using Computational Fluid Dynamics and 3D Finite Element Method in Ansys CFX and Ansys Maxwell 3D respectively. Then, a Face Mock-Up Interface (FMI) is set up for both models which were coupled in Ansys Twin Builder. Finally, the NTSMC is applied on the DC side through a Boost Converter in order to have a less complex control algorithm which can be easily implemented on a microcontroller. Simulation Results show the performance of the proposed method and comparisons with conventional controllers in order to demonstrate its robustness and fast response.

With the increase installed capacity of wind energy, conventional generation starts to be replaced by wind farms, which will results in erosion of system frequency. It is thus imperative to develop advanced wind turbine control method to maintain the frequency. Considering the calculating complication of full-order models, this paper proposed a reduced wind turbine model with optimal dynamic performance. In order to improve the performance of the whole wind farm in frequency control, this work proposes a coordinate method at constant power control model for the goal of optimal dynamic response of the wind farm, considering the differences in operation state and wind speed of each wind turbine. Finally, the correctness and effectiveness of the proposed method are validated by the simulation.

Information system data transmission delays, packet loss, and bit errors will cause the information collected by the distribution network control center to deviate from the true value, and as the information failure problem intensifies, the original optimized control strategy cannot meet actual needs. A predictive control method considering the information failure of the distribution network under the cyber-physical fusion system is proposed. Aiming at the information failure problem in CPS, the information elements, routing model and link model are established. Then, combining with the real-time dispatching process of distribution network, a coordination optimization model of active distribution network considering information failure is proposed to minimize the cost. Predictive control model is used to adjust various distributed energy sources. Finally, through the simulation analysis of the improved IEEE33-node distribution network, the feasibility and effectiveness of the proposed method are verified, and the difference of different information failure cases is analyzed.

The fluctuation and the randomness of REG's output have severe impacts on the safety and stability of the operation. To guarantee a stable operation of the distribution system, the important impacts of the REGs on the safety operation of the distribution system are analyzed in six aspects, including the power transmission, the power quality, the frequency stability, the islanding effects, the protection,and the planning. To cope with these impacts, the corresponding suggestions, such as the formulation of a comprehensive safety and stabilization guide, the optimization of the network structure, and the improvement of the REGs' stability and controllability, are proposed.Particularly, the coordinated planning method for the distribution network is discussed in detail. The in-depth analysis of the planning model is presented.
