Transformers neutral grounding accessing small reactance is an effective measure to restrain short circuit current in 500kV power grid. But accessing small reactance will bring changes to the zero-sequence parameters of system. The relay protection, especially the main transformer protection and transmission line protection nearby will be affected and act incorrectly when unsymmetrical earth fault occurs in the transmission line. An equivalent system model based on the Guangdong power grid's actual parameter and autotransformer in 500kV substation is built, the effects on power system's zero-sequence parameters as only one autotransformer neutral point grounded via small reactance is analyzed Meanwhile, a quantitative calculation is accomplished based on the relative variation of zero-sequence components from three aspects: fault position, resistance value and transmission line length. Furthermore, the effects on protective relaying and coordination between the adjacent lines are analyzed according to curves drawn by Matlab. Zero-sequence current protection of autotransformer neutral should be reset to meet sensitivity.

Building an equivalent model of small and mediumsized hydropower generator group is a practical method carried out for dynamic analysis of water electricity grid. Excitation and governor system have prominent influences on the precision of the equivalent model. This paper presents a method to build a dynamic equivalent model of hydropower generator units containing excitation and governing system, the method uses traditional equivalent model of hydropower generator group which is based on homology method as the foundation, and considers the equivalence of excitation and governor system. It uses PLPF method to get the equivalent parameters of excitation system and weighted average method to get the equivalent parameters of prime mover and speed governor. Numerical examples show that deviation of the method in dynamic process is smaller, and it can improve the simulation accuracy. On this basis, further simulations are made to analyze the effect of excitation and governor system on dynamic characteristics.

In recent years, with rapid development of low voltage photovoltaic(PV) microgrid, control and protection technology associated with low-voltage microgrid has been the focus of research. Microgrid with its power can flow in both directions and fault current differs in the grid-connected mode and islanded mode, takes a great challenge to the traditional protection technology. To solve this problem, this paper proposes a new strategy to protect microgrid using the fault direction information, determines the switch's fault direction through the energy function, locates the external fault, common bus fault and feeder fault using fault direction information based on stratification searching thought. For the feeder fault location, this article creates direction information matrix, switch-branch matrix and branch-switch matrix, to achieve fast feeder fault location and action through the matrix operation. The Simulation results show that, the micro-grid protection strategies propose to achieve fast fault location and isolation, effectively protect the security and stability of low voltage photovoltaic microgrid.

Based on analyzing of the full-range wind power curtailment control (WPCC) operation characteristics, a novel WPCC (N-WPCC) strategy is proposed in this paper. The corresponding controller is presented, which consists of a rotor speed controller, a torque controller, a pitch angle and its compensation controller. Theoretical analysis and simulation results show that, through giving priority to the torque control than the pitch regulation compared with the traditional WPCC, N-WPCC can effectively decrease the pitch angle regulation frequency and amplitude, thus to extend its operating life, and can also improve the power generation to some extent because of taking the full advantage of the vast rotational inertia of turbines. In addition, output power and rotor speed are the control inputs for the proposed method, without the need of the wind speed.

The power grid in China has a series of problems of aged infrastructure, lack of resources and increased energy demand. The construction of smart grid is an important way to solve the above problems. The energy management and optimal adjustment in distributed power grid is the key for the system function realization, and several issues should be addressed: how to effectively manage the uncertainties of the intermittent power sources; how to manage the energy transferring equipment and diversities of the load varieties; and under different operational constraints, how to realize the high-level unification for multi-source distribution network economic operation and the reliability of power supply. The project will focus on these tasks based on load models considering the dual direction of the information between the energy suppliers and end users. It can reduce the energy generation cost, improve the energy quality, decrease the tariff, carbon emission and satisfy the user demands. The research will provide new infrastructure and technology support to smart grids with broad industrial application prospect.

For the reliability evaluation of distribution network with wind power, the current application of different simulation methods have a common contradiction between accuracy and computational time. In this paper, a method for the reliability evaluation of distribution network based on Wasserstein distance multi-scene is presented. First, optimal quintile and its probability of wind power scenes are determined by probability distribution of wind speed and wind turbine power curve. Second, the feeder partition algorithm is applied to calculate the reliability indices of distribution network under different scenes. Finally, the total probability formula is used to calculate the reliability indices of distribution network with wind power. A comparison with the results of Monte Carlo simulation method shows that the proposed method is simple and efficient, having high accuracy and suitable for evaluating reliability of distribution network that encompasses wind power.

The wide application of electric arc furnace (EAF) loads usually cause negative effects in the grid, especially drastic voltage fluctuation. Chaos theory is used to study ac EAF voltage fluctuation mechanism in this paper. Firstly, C-C method is adopted to reconstruct phase space of voltage time series. According to BDS(named after Brock, Dechert, and Scheinkman) statistics, the optimal delay time and embedding dimension are determined. Then, trajectory divergence rates in the phase space are calculated by improved Wolf algorithm as nearest points evolve along the trajectory. By fitting these divergence rates through least square method, the maximum Lyapunov exponent (MLE) is obtained. Results show that the voltage fluctuation of ac EAF has chaotic property, which lays the foundation for analysis and prediction of voltage fluctuation using chaotic method.

Application of energy storage system (ESS) has been a chance and challenge to distribution system operation and integration of renewable energy sources (RESs). A conic programming (CP) based method is proposed for the optimization of distribution system with ESS in this paper. Firstly, the operation optimization model considering the state of charge (SOC) of ESS is built to minimize the active power losses of distribution system with distributed generation (DG). Equivalent CP model is conversed based on the initial model as format required, which can be solved by some mature optimization tools. Finally, case studies show the feasibility as well as effectiveness of the proposed method.

Multi-type generators peaking problem has always been difficult to the researchers, since there are different generator models and complex constraints. In this paper, a decoupled multi-generator peaking model is proposed and used for control strategies. Also, the peaking control strategies are acquired through quantitative calculation and qualitative analysis. Quantitative calculation gives the output schedule for each unit or plant, while qualitative analysis analyzes the influence of different factors on peaking strategies, and the coordination method of various source types. Deep peaking of thermal units is taken into consideration and a bi-level optimization model is used to solve the thermal subsystem. The index of equivalent start-stop peaking capacity is defined, based on which the coordination method of multi-power peaking strategies is proposed.
