  • DC-Bus Voltage Control Stability Affected by AC-Bus Voltage Control in VSCs Connected to Weak AC Grids

    With the wide application of voltage source converters (VSCs) in power system, dc-bus voltage control instabilities increasingly occurred in practical conditions, especially in weak ac grid, which poses challenges on stability and security of power converters applications. This paper aims to give physical insights into the stability of dc-bus voltage control affected by ac- bus voltage control in VSC connected to weak grid. The concepts of damping and restoring components are developed for dc-bus voltage to describe the stability of dc-bus voltage control. The impact of ac-bus voltage control on dc-bus voltage control stability can be revealed by investigating the impact of ac-bus voltage control on damping and restoring components essentially. Furthermore, the detailed analysis for the impact of ac-bus voltage control on damping and restoring components is presented considering varied ac system strengths, operating points, and ac-bus voltage control parameters. The simulation results from 1.5-MW full-capacity wind power generation system are demonstrated which conform well to the analysis. Finally, the experimental results validate the analysis.

  • Secondary voltage control of power grid using voltage stability index and voltage control areas

    This paper presents secondary voltage control of power grid using identification of voltage stability index and voltage control areas. Unlike, the traditional secondary voltage control in North America performed directly by switching capacitor banks and other reactive power sources, in the proposed approach generators are chosen first to perform secondary voltage control. The participation of generators in secondary voltage control increases the utilization of reactive power capability of generators as well as decreases the requirement of additional reactive power sources. To perform the control, the power grid is divided into voltage control areas using reactive power sensitivity method. A new technique of secondary voltage control with stability index is presented using vulnerability test considering all buses instead of just the pilot bus. The method is implemented on IEEE 39 bus system for secondary control when subjected to a disturbance and the simulation results are presented.

  • Static Hybrid Automatic Voltage Control Systems

    The concept of hybrid power control system is introduced to the power systems' voltage control, and the static hybrid automatic voltage control (HAVC) system has been established in the paper. Firstly, we set up a new hybrid hierarchical voltage control system model based on the hybrid theory, and design the operating process. Then we define the stability event and the economic event to drive the system, through which we achieve the synthetic objects of safety, stability and economy. Moreover, the system provides a much easier access to achieve optimal automatic voltage control, thus highly feasible in practice. The system's controlled targets, which are driven and decoupled by discrete events, are dispatched to different modules of sub- layer, so that the calculations become more efficient with better use of available technologies. Computer simulation results have proven the validity of the system and the approaches designed in the paper.

  • Voltage control practices and tools used for system voltage control of PJM

    PJM has developed a pilot program of on-line (real time) voltage control in which a system wide Optimal Voltage Control (OVC) demonstration system has been implemented and run on-line parallel with PJM existing system at PJM control center since Jan. 2010. The pilot program was for nine months. The OVC system consists of Data I/O Management, Control Strategy Calculation, Operation Log Management and Control Process Dispatch. It is interfaced with PJM EMS system, automatically receives real-time snapshot from PJM EMS periodically, and calculates optimal voltage schedules for each generator, LTC and switchable shunt in the PJM system. The practices, experiences and results of the pilot program are presented in this panel paper. Significant potential benefits can be achieved with OVC techniques in both aspects of security and economy: (1) average reduction of transmission system loss is about 1.19%, which means energy savings of more than 220 million kWh/year and monetary savings of more than $17 million/year; (2) Average increase of system VAR reserve is about 1.08%; (3) Improvement on system security for pre-contingency and post-contingency is significant, including improvement on these security indices in voltage limits violations, and voltage stability limits violations.

  • Online Supervisory Voltage Control for Grid Interface of Utility-Level PV Plants

    Large-scale photovoltaic (PV) plants are being designed to support grid- voltage regulation. Based on transmission-level interconnection, this paper proposes a novel online supervisory voltage control (OSVC) strategy to improve network voltage profiles. The system structure includes the algorithms for reactive power allocation and online voltage tracking. The effectiveness of the proposed OSVC that improves the network voltage profile is verified by simulation in comparison with the conventional line-drop secondary voltage control and primary voltage control. Since the application relies on the measurement and communication network, the time delay is considered. Based on the available bandwidth of the wide-area measurement systems (WAMSs), the simulation shows the feasibility and success of utilizing the OSVC for real- world implementations. The study also indicates the transient response can be improved further by the proposed solution when high-bandwidth WAMS infrastructures are available in the future. Furthermore, the proposed control strategy is tested in a weak power network with the low-short circuit ratio and failure of communication.

  • Line drop compensation, high side voltage control, secondary voltage control-why not control a generator like a static VAr compensator?

    Generators typically regulate terminal voltage via automatic voltage regulator and exciter equipment. The desired high side (transmission side) voltage schedule is usually maintained by the power plant operator or by slow SCADA- type process control computers. Power system dynamic performance, however, can be improved by faster regulation of the transmission voltage. Contrasted to generators, static VAr compensators are designed specifically for transmission voltage regulation. The transmission voltage is directly regulated at high speed. Total SVC and medium voltage component reactive power ratings are referred to the transmission side. All medium voltage equipment are designed to support the transmission side reactive power and voltage regulation requirements. The droop (slope) setting is usually small compared to generators regulating terminal voltage. This paper introduces the panel session on secondary voltage control. The author outline various methods for tighter high side voltage control, with emphasis on control of hydro generation in the US Pacific Northwest.

  • Comparing a novel optimal coordinated voltage control and secondary voltage control

    This paper deals with the comparison between an optimal coordinated voltage control (OCVC) and secondary voltage control (SVC) for long-term voltage stability enhancement. OCVC model in this paper is based on quasi-steady-state (QSS) approximation, including continuous and discrete time differential- algebraic equations (DAEs). This model considers long-term voltage stability and costs of controls synthetically, which can coordinate different kinds of controls distributed over different locations. Pontryagin maximum value principle and Radau collocation method are applied to solve the OCVC model. Besides, in order to consider discrete characteristics of transformer tap control, capacitor switching and load shedding, a quadratic penalty function mechanism is incorporated to this control model. SVC model used here is a simplified version of Italian type, which is simulated by PSAT (Power system analysis toolbox). With the simulation results on New England 39 buses system, we can see that OCVC has better voltage profile, better use of reactive power resources and better capability of maintaining long-term voltage stability after disturbances.

  • An affine arithmetic method to identify Voltage Control Areas for Secondary Voltage Control

    This paper aims to present a methodology to identify Voltage Control Areas (VCA) for Secondary Voltage Control (SVC). The proposed methodology consists in the representation of data uncertainty using Affine Arithmetic (AA) applied to the Power Flow Analysis. The uncertainty used in this paper is associated only with reactive power demand, mainly due to forecast errors. The IEEE 14 bus test system and the IEEE 118 bus system are used to evaluate the proposed methodology and the results presented validate and indicate the effectiveness of using an AA-based method to identify VCA.

  • Dynamic Hybrid Automatic Voltage Control of the power system

    According to the dynamic voltage security control, the concept and method of the hybrid control system are introduced, and the dynamic hybrid automatic voltage control (D-HAVC) system is realized. The hybrid hierarchical control system model based on the hybrid theory is set up firstly. In the modelpsilas high layer, the power systempsilas differential-algebraic-equations are linearized, and the eigen-matrixpsilas minimum amplitude eigenvalue (MAE) is used to judge the power systempsilas voltage security. Through this way, the discrete events are formed and used to drive the control block. In the modelpsilas middle layer, under the discrete event driving, the control values of the control buses are calculated with the sensitivity method, and are formed as the control strategy through the interface block. The control equipment in the bottom layer receives the control strategies and perform them, and the closed automatic voltage control is achieved. Computer simulation comparisons with secondary voltage control (SeVC) have proved the solution effective in realizing D-HAVC system.
