China is increasing its efforts in implementing demand side management (DSM) programs as a method to reduce peak electricity demand and match demand with renewable resources. These efforts are motivated by the country’s ambition to address several challenges, including emission reduction, renewables integration, peak shaving, and improving load factor and ambition for net zero emission. DSM service-providers are the enterprises that orchestrate DSM events alongside of the power system operator and end-users to achieve DSM goals. This paper presents a comprehensive study of the market, opportunities, and the challenges facing the emerging DSM market in China. The ongoing reform of China’s power system and the effects on the DSM market are discussed. The most notable DSM project in China in recent years are presented. The challenges and opportunities for the DSM specific to China are discussed.

While the marine transportation industry is responsible for most global transportation tasks, it also accounts for a large proportion of greenhouse emissions. With the goal of carbon neutrality, emission control and marine carbon trading scheme are developed. Transportation ships will be subject to the emission control area with multiple protection levels. In this paper, a hierarchical optimization method of ship integrated power system (IPS) is proposed to reduce transportation costs by splitting the optimization problem via different time scales. Then, the operation problems of the ship’s powertrain and power system are solved, respectively. The cost of the proposed method and the traditional constant navigation schemes are compared. The results show that the proposed method can reduce the total cost of the route by adjusting the speed flexibly according to different protection levels in each control area.

Power system with high integration of wind power appeals to be increasingly complicated in system simulation. It is meaningful to establish an accurate and convenient model considering dynamic characteristics of wind farm connected to power system. In this paper, an equivalent model is proposed focus on the high voltage ride through (HVRT) features of wind turbines. Firstly, the structure of wind power via high voltage direct current (HVDC) is investigated, and then the transient control strategy is designed in accordance with the grid code. Secondly, we select pre-fault voltage, active power, wind speed, post-fault voltage and action of chopper as input variable matrix according to mathematical model. On the basis of selected variables, the equivalent group number is obtained by using max-min distance clustering method. And then the multi-machine equivalent model of wind farm is built based on the clustering results. Finally, according to case verification of 15-turbine wind farm, the proposed equivalent model can reflect HVRT operating characteristics of wind farm more accurately.

The multi-terminal hybrid ultra-high voltage direct current (MTH-UHVDC) transmission technology combining line commuted converter ultra-high voltage direct current (LCC-UHVDC) technology and modular multilevel converter ultra-high voltage direct current (MMC-UHVDC), provides a more flexible and advanced mode to meet the needs of longer distance and larger capacity clean energy transmission. Compared with the two-end HVDC system, the control and protection (C&P) functional and dynamic characteristics of MTH-UHVDC transmission system are more complex. The real-time simulation technology must be used to carry out the experimental research before the engineering application. However, the hardware in loop (HIL) real-time simulation test of MTH-UHVDC transmission system is faced with many technical problems, such as multi-type interface of test system, accurate modeling of UHVDC MMC valve, full access of C&P devices, etc. Therefore, from the perspective of simulation test research and engineering application, this paper proposes a HIL real-time simulation test method for C&P system of MTH-UHVDC transmission system. The design of test system, accurate modeling of primary system, modeling of C&P system, interface technology of test system, functional and performance test method of C&P system and engineering application are deeply studied. Taking kunliulong project, the world’s first MTH-UHVDC project, as the application background, a real-time simulation test system for C&P system is established by the proposed method. The functional performance test (FPT) and dynamic performance test (DPT) are carried out using the established test system, and the simulation test waveforms are compared with the field test waveforms. The results show that the response characteristics of the two systems are consistent, and the test system established in this paper can meet the needs of accurate real-time simulation test and research, and can provide technical support for the application of MTH-UHVDC technology.

In order to study the detection effect of optical detection on corona discharge in gas insulated switchgear (GIS), a photomultiplier tube (PMT) based optical detection method test platform is built. The needle-plate electrode is used to simulate corona discharge. An oscilloscope is used to collect the optical signal of corona discharge, a high-voltage probe is used to obtain the reference voltage, and the phase resolved partial discharge (PRPD) pattern of the optical signal is analyzed. The results show that with the development of partial discharge (PD), the PRPD pattern can obviously unfold in different stages, which indicates that the optical detection for GIS has high detection sensitivity and good discrimination of the severity of discharge development. By combining the results of the PRPD pattern and previous studies, it is inferred that the negative half cycle discharge of AC corona discharge mainly depends on the electron avalanche ($alpha$-process) and the secondary electron avalanche on the cathode surface ($gamma$-process), and the light radiation is mainly excitation radiation and bremsstrahlung. The positive half cycle mainly depends on spatial photoionization (anode streamer), and the light radiation mainly consists of recombination radiation, excitation radiation and bremsstrahlung. This paper can provide a reference for the application of photoelectric devices used in GIS.

Large-scale renewable energy integrated to the power system will lead to transient voltage instability. This paper investigates capacity configuration of synchronous condenser for a sending end system integrated renewable energy model to improve its transient voltage stability. Following the overview of the sending end system and model of synchronous condenser, two comprehensive index of transient voltage stability for sending end system integrated with high penetration renewable energy are proposed, which combines both transient voltage stability and transient voltage instability risk. The transient voltage stability index is measured by the maximum and minimum value and duration of the transient voltage, and the transient voltage instability risk index is measured by the time-voltage area. Considering the proposed comprehensive index together with the economic cost as optimization objective, an optimization model is formulated to configurate the capacity of synchronous condenser, which is solved with Cplex solver. Finally, the case study verification is carried out on a high voltage direct current based sending end system with high penetration of renewable energies. Simulation results verify that the optimized capacity configuration of synchronous condenser can improve transient voltage stability of the system effectively.

Distributed Energy Resources (DERs) are gradually becoming dominant sources of generation in modern power systems. From a system resilience perspective, the distributed nature of such resources helps in forming islanded microgrids during grid contingencies. Therefore, a robust synchronization mechanism is needed to synchronize the autonomous islanded microgrid to the utility grid. As grid forming inverters (GFM) help in establishing the voltage and frequency of an islanded system, it is necessary that a strategy is developed to follow the utility grid’s voltage magnitude and phase during reconnection after contingency events. In this paper, a synchronization strategy is developed which translates the operation of a GFM from a master mode to a slave mode without requiring any change in power production philosophy. The proposed method does not require alteration of existing control strategy, thus preserving the true characteristics of a GFM system. The technique is validated in the modified IEEE 9-bus system and the EMTDC/PSCAD simulation results demonstrate the seamless transition effect of the proposed strategy.

Floating photovoltaic (FPV) is a novel sustainable power generation component that combines renewable energy and marine technologies to generate electric power eco-friendly. This paper proposes the optimal configuration and the economic-environmental analysis of future FPV installation in Singapore, one of the representative countries with ample solar power resources and water bodies worldwide. First, the technical feasibility of FPV installation in Singapore is analyzed. Next, a suitable location in Singapore to install FPVs, i.e., Pandan Reservoir, is determined. Then, a sensitivity analysis is conducted under four FPV configurations (i.e., monofacial FPV, monofacial FPV with heatsink, bifacial FPV, and bifacial FPV with heatsink). Results showcase how FPV efficiency can be improved and suggest the optimal FPV configuration at the desired location. Finally, the economic and environmental aspects of FPV installation in Singapore are elaborated. This study could help policy-makers set developmental goals for future large-scale FPV integration and guide industry practitioners to adopt FPVs.

Vanadium redox flow batteries (VRBs) are promising energy storage systems suitable for large-scale solar-battery integrated electric vehicle charging stations. Such a system can mitigate the impact on the grid system due to high and random charging power demand. In this application, an accurate estimation of the peak power of VRBs is the premise of its safe and efficient operation. This work thus proposes a peak power estimation method based on economic model predictive control (EMPC) is thus proposed. This method first establishes an integrated equivalent circuit model consisting of an electrical and a hydraulic submodel. With the model, the state of the VRB and terminal voltage can be accurately predicted under given input excitation. Then, the receding optimization method is carried out based on the VRB model and estimated state. Finally, the proposed EMPC-based peak power estimation scheme is numerically verified via computer simulation. The results show that by optimizing the current and flow rate of the VRB, a safe operating area for charging electric vehicles can be obtained for practical use.
