Mobilizing users to participate in Demand Side Response (DSR) is an inevitable requirement for the construction of the Energy Internet. The user's demand response characteristics shape the user's ability to reduce the total amount of electricity bills and control the risk of electricity bill fluctuations in an environment of uncertain electricity price fluctuations. Different users have different risk preferences, and because different users have different production characteristics, the difficulty of adjusting their electricity consumption behaviors in each time period is also different. Based on the aforementioned two reasons, users need personalized demand response characteristics to maximize their own utility. Based on the modeling of user response behavior and the simulation of electricity price risk environment based on MCMC sampling method, this paper designs a method that can optimize the demand response characteristics of different users according to their risk preferences and production characteristics with the help of Genetic Algorithm.

To calculate the current stress of each device of the three-phase quasi Z-source inverter, this paper proposes to calculate the current stress of all devices of the Quasi-Z-source inverter model by mathematical analytic Cauchy–Schwarz inequality. Because the quasi Z-source inverter is nontraditional, the current of the device consists of two components: high frequency and low frequency, which makes the calculation of current stress relatively complex. This paper proposes to separate these two components and calculate their current stresses. The average and effective values of current in Quasi-Z source network devices and inverter bridge switching devices depend on the load current and through current. Based on this, the current stress and capacitance-voltage stress in the Z source impedance network and quasi Z-source impedance network are compared. A system simulation model is built in the MATLAB/Simulink, and the results verify the feasibility of the proposed theoretical analysis.

In a battery energy storage system (BESS), an accurate estimation of state-of-charge (SOC) is of great significance to prevent batteries from over-charging or over-discharging. However, existing SOC estimator implemented in battery management system (BMS) may suffer from significant error, accumulating along with time. This paper discusses an online approach to refine SOC estimation from BMS, taking advantage of historical operating data. After locating SOC reference point from historical time-series data, the maximum available capacity of charge or discharge is tracked online using a weighted least squares (WLS) formulation. Then, a refined SOC value can be determined by coulomb counting. Based on the operation data from a practical BESS, the proposed SOC refining approach is proved to be effective in providing a more accurate estimation.

Studies and practices indicate that new energy power generation (NEPG) such as wind and photovoltaic power may cause subsynchronous oscillation (SSO). A typical event caused by wind farms occurred in Qomul, Xinjiang, China, in July 2015, which led up to three steam turbines tripped off the grid in succession, and the ±800kV Qomul-Zhengzhou HVDC had to suffer a large power plummet. Different from similar phenomena relevant to steam turbines with series compensation or HVDC, the oscillation frequency due to NEPG is not a constant, but a variable value in a broadband. This characteristic makes it difficult to be effectively and economically suppressed. Nowadays in China, bursting synchronous condensers (SC) are more common to be installed in HVDC rectifier stations to provide reactive power and voltage support, and distributed synchronous condensers are employed more widely in new energy plants to improve voltage safety and stability of the grid. This paper proposes a new suppression method for SSO caused by NEPG, that is to append a subsynchronous oscillation damping control loop to the excitation system of the synchronous condensers, which are already employed in NEPG bases and HVDC rectifier stations. Simulation work has been carried out to verify the suppression effect preliminarily.

The rapid growth of distributed photovoltaic brings great threat to the safe operation of power system. Flexible resources can adjust the local power balance, but there is no corresponding policy in China to encourage flexible resources to participate in power system operation. At present, China is promoting the marketization development of distributed power generation. Therefore, this paper proposes to build a P2P energy market in the local network with distributed photovoltaic. Trading mechanism can encourage users to schedule flexible resources reasonably. It can improve the operating state of the system and increase the photovoltaic accommodation rate. The MMR pricing method was used to allocate benefits within the market. The results showed that the P2P energy market was able to promote prosumers to use flexible resources and increase the hosting capacity of distributed photovoltaic power stations. At the same time, market participants improved economic benefits.

The access of new energy will bring many problems to the traditional power system. Bundled delivery of new energy can weaken the adverse effects caused by wind energy and solar energy fluctuations, and is smoother and more controllable than pure wind power or photovoltaic output. In this paper, the framework of the wind-PV-thermal-bundled power transmission is constructed, and the simulation model of the system is established based on MATLAB / Simulink. The control strategy of STATCOM with power oscillation damping (POD) is proposed, and the parameters of STATCOM-POD controller are coordinated and optimized with damping ratio as the objective function. Eigenvalue analysis and simulation results show that the controller parameters optimized by the proposed method can effectively improve the damping ratio of the system, and the overall damping characteristics and dynamic stability of the system can be effectively improved through parameter coordination and optimization.

The multi-terminal high voltage direct current (MTDC) grids make it possible to connect large scale clean energy to the grid. However, the lack of effective methods minimizing the DC line faults impact limits the development of MTDC grids in some extent. This paper first analyses the propagation characteristics of the fault traveling wave in DC line. Then, the expressions of the initial line-mode fault current traveling wave (ILCTW) under typical internal and external fault are obtained. Moreover, a fast nonunit protection scheme is proposed based on the filtered fault transient current traveling wave. A modular multilevel converter (MMC)-based four-terminal high voltage direct current (HVDC) grid is established in PSCAD/MTDC, and extensive simulation results are conducted to validate that the protection scheme can not only identify the internal fault accurately and rapidly, but is also effective in detecting different fault locations and large fault resistance.

The rapid expansion in the power system has led to substantial growth in the number of transmission overhead lines in service over the past decades. These lines encounter faults that must be mitigated before returning the line to operation to recover the consumers’ connection. The repair can be accelerated if the pinpointing of the fault can be determined with sufficient precision. The exact determination of the position of transmission line faults has been a challenge for service engineers, designers, and researchers over the last few years. Thus, the fault locating technique allows engineers to pinpoint where the fault occurred in a highly logical timeframe. This fault locating method is required to pinpoint where the fault on the power lines occurred. Several transmission lines are 100 kilometers long; thus, making it time-consuming to find the fault’s position. The longer it takes the field engineers to find the fault locality, the higher production losses. Therefore, it is essential to pinpoint the exact locality of the fault to save time and money. The paper proposes a model developed in MATLAB software to study the faults that exist in the transmission line. The model consists of a fault location detection element to pinpoint the exact position of the fault on the line. This paper focuses on fault tracking on the transmission overhead line utilizing a conventional approach. The model will be improved utilizing advanced methods to improve the overall speed and accuracy.

Low voltage multi-terminal DC system is one of the essential network structures to access a large portion of distributed energy in and improve the system reliability and capacity of power supply. The system stability has attracted widespread attention. This paper describes the representative system structure, and constructs the coordinated schemes of system control like master-slave control mode and droop control mode. On this basis, the impact of AC faults on DC network is analyzed under different control strategies. A MATLAB/Simulink simulation model is established for example verification, and the corresponding test platform is built for experimental verification. The research in this paper can provide an effective method to analyze the interaction of low voltage system with multiple ports, and this method can be used to design and integration test of system control strategies.
