In the traditional vertically integrated electric utility, the generators always provide the reserve without any payment. In the electricity market, it is necessary to encourage the generators to provide the reserve through one scientific and reasonable reserve pricing mechanism. The reserve Aumann-Shapley pricing mechanism is put forward in this paper, with the analysis of the costs and benefits, the mutual costs and benefits of the energy and the reserve are allocated basing on the Aumann-Shapley value firstly, and then the reserve prices under the competitive energy market are formed, the joint optimization model of the energy market considering the reserve Aumann-Shapley price is founded, and the influence of the reserve Aumann-Shapley price on the generators' bidding strategies is analyzed. The reserve Aumann-Shapley pricing mechanism is applicable to the actual model of the electricity market in China, at the same time, the study gives a new idea of the ancillary service pricing in a deregulated electricity market.

More and more conventional grounding systems made of steel are being replaced with copper grounding systems in Asian countries. This paper analyzes the performance of grounding systems made of steel or copper conductors, taking into account the impedances of the ground conductors. A series of computer models simulate grounding systems of different sizes in various soil structures. Numerical results such as ground impedance, ground potential rise (GPR), touch and step voltages, and potential differences between copper ground conductors are compared with those pertaining to steel grounding systems. The performance advantages of grounding grids made of copper are demonstrated throughout the comparison. This paper also presents briefly a practical grounding performance before and after the replacement of steel with copper conductors.

The thyristor controlled series capacitor (TCSC) has been well known as a potential countermeasure against SSR since it was introduced. This paper uses a real case, a local power plant connected to a remote load center through a series compensated radial transfer corridor, as an example to illustrate the capability of TCSC to mitigate SSR. The TCSC uses a special patented control scheme called synchronous voltage reversal (SVR). The paper is organized into three parts. Firstly, modal analysis is applied to obtain the natural torsional modes of the shaft spring mass model. Secondly, simulation of the generator and the connected electric network is performed, when a small modulation of the generator shaft speed within the SSR frequency range has been applied. As a result the electrical damping can be obtained from the calculated electrical torque. The scanning results under different scenarios show that the units using a fixed series compensation scheme are highly exposed to SSR risk. A novel scheme with TCSC is proposed and the result of frequency scanning shows very good SSR damping performance, where SVR counteracts the most part of the electrical damping of the modes at risk. Furthermore, an add-on control strategy can be easily introduced to pull the remaining slight portion into a secure range. Simulation results with detailed shaft spring-mass model validate TCSC control effect and the feasibility of such transmission schemes.

The wide-area backup protection algorithms based on multi-agent have been developed during recent years. Based on these known algorithms, the cooperative modeling and design mechanism of multi-agent is studied to construct novel protection system in this paper. The abstract concept and principle of the agent are embodied; organization-based collaboration of multi- agent is proposed to improve the protection system's intelligence and abilities of eliminating the misoperation and reject of protection. Some design mechanisms of the agent are given for the wide-area backup protection, such as agent's internal three- layer structure, functional modules, equal organizational structure, the negotiation protocol, and three fault-tolerance measures. The state diagram and collaboration diagram are adapted to analyze interaction behaviors among agents. An example is given to explain the negotiation procedure while all protection operations in an agent are failing. Another example explains how multiple agents cooperate to find and lock the misoperation of III line protection made by transmission line overload. These examples illustrate the reasonableness of the design mechanism of the agent.

Prony algorithm can be used in online identification of power system low-frequency oscillation, but it is sensitive to the noise of the analysis data which will affect the analysis precision extremely. In this paper, a fuzzy filter and Prony algorithm based hybrid method is presented to identify the modes of low-frequency oscillation. Because the fuzzy filter can cancel the mixed noise rapidly and easily by fuzzy logic, the dominant mode of the low-frequency oscillation can be obtained relatively easily by Prony algorithm this time. Simulation results on active power oscillation of branch 302245 in Center China Power Grid (CCPG) and comparison results of different methods demonstrate the proposed method can provide more precise analysis results and prove its validity.

Based on hybrid control theory, this paper introduces an integrated control strategy of voltage and reactive power in substation. This strategy adopts the hierarchical balance optimization of reactive power and improves the traditional "nine-area diagram" control method. The new hybrid control strategy not only solves the oscillating problem caused by the change of transformer taps and shunt capacitors switching, but also responses the global optimal control command of reactive power in time. The simulations have proved the validity of the HAVC strategy.

The present paper is concerned with stabilization of a power system with WPGS (wind power generation system) by active power control of a number of micro SMES units. The sample power system for simulation includes three hydro power stations including two pumped storage stations, two wind power generation stations and long transmission lines. Wind velocity variations are assumed, and a performance index is defined with the oscillations of synchronous generators taken into account. In order to obtain the optimal allocation of micro SMES units of predetermined number, genetic algorithm (GA) is adopted based on the defined performance index, and the results are compared with that obtained by Tabu search (TS).

The multi-functional flexible power conditioner (FPC) is a novel FACTS device, which consists of a large-mass varying-speed energy storage flywheel and a double-fed induction machine (DFIM). The FPC can be used to compensate the dynamic unbalanced power of the power system following disturbances using the energy stored in the flywheel by controlling the rotor speed. With an appropriate control strategy, the FPC is able to realize an independent active and reactive power exchanging with the connected power system. Similar to the superconductive magnetic energy storage (SMES), the FPC can be used to improve the stability of power system and the quality of the power supply. As it is difficult for the conventional stator flux oriented control (SFOC) to give satisfactory robustness of the FPC against the grid voltage fluctuation in this particular application, an improved SFOC is developed. A state space displacement model in terms of d-q components is deduced from the linearized equations, which is used to describe the small signal dynamic performance of the doubly fed induction machine. The system eigenvalue analysis result shows that the dynamic performance and the stability operation regions of the FPC are influenced mainly by the rotor speed, the grid voltage fluctuation and the rotor excitation control. The slip stability rather than the angular stability seems to dominant the stability characteristics of the FPC. A small slip absolute value will give a more stable FPC. Investigation results also show that the dynamics of the stator currents on the performance of the FPC is neglectable and therefore a third order reduced model is enough to represent FPC for approximation. This simplifies the design of the excitation control. Further more, it has been verified by simulation that the improved SFOC provides better system performance than the conventional SFOC during the grid voltage fluctuations.
