Abstract: This invention presents a method of novel nonlinear control for designing Static Synchronous Compensators (STATCOM). A passivity-based approach is proposed for designing robust nonlinear STATCOM controller. The mathematical model of STATCOM will be represented by an Euler-Lagrange (EL) system corresponding to a set of EL parameters. By employing the Park's transformation, the differential geometry approach is used to investigate the power system dynamics with considering STATCOM under the synchronous d-q frame. The energy-dissipative properties of the proposed model derived in the synchronous d-q rotating frame are fully retained. This model also consider the dynamic response of the changable load. Finally, the passivity-based control is employed by using energy shaping and damping injection techniques to produce the proper control signals for Voltage Source Converter. So that the system embedded with STATCOM is more robust and stable.

Abstract: Power flow models of Interline Power Flow Controllers (IPFC) for large-scale power systems are studied, in details. Mathematical models of the IPFC, using the d-q axis decompositions of control parameters are derived. In this framework, for each IPFC, only two control parameters are added to the unknown vector in the iteration formula and the quadratic convergence characteristic is preserved. Simulations results from several practical large-scale power systems embedded with multiple Convertible Static Compensators (CSCs) demonstrate the effectiveness of the proposed models. Comparisons with existing models are made to elucidate the performance of the convergence.

Abstract: The power flow model of the multiterminal voltage-source converter-based high voltage DC (M-VSC-HVDC) transmission system for large-scale power systems is studied. The mathematical model is derived using the d-q axis decomposition of HVDC's control parameter. The developed model can be applied to all existing shunt voltage-source converter (VSC) based controllers, including Static Synchronous Compensator (STATCOM), point-to-point HVDC system, back-to-back HVDC system and multiterminal HVDC system. A unified procedure is developed for incorporating the proposed model into the conventional Newton-Raphson power flow solver. The IEEE 300-bus test system embedded with multiple HVDC transmission systems under different configurations are investigated. Simulation results reveal that the proposed model is effective and accuracy in meeting various control objectives.

Abstract: Given the current operating condition at each bus from real-time database, from the short-term load forecast, or from near-term generation dispatch, we present a method for real-time contingency prediction and selection in current energy management systems. This method can be applied to contingency prediction and selection for the near-term power system in terms of load margins to collapse and of the bus voltage magnitudes. The propose algorithm uses only two tangent vectors of power flow solutions and curve fitting based techniques to perform look-ahead load margin and voltage magnitude simultaneously. Therefore, it can overcome the traditional snap-shot contingency analysis methods. Simulations are performed on IEEE 57 and 118-bus test systems to demonstrate the feasibility of this method.

Abstract: The present invention is a supporting structure for decorative Christmas lights. The main structure of the present invention is a center pole with a fixed hub at the top, and a movable hub, which can move along the center pole. A plurality of hanging bars are connected to the fixed hub at one end, and connected to the supportive struts at the other end. The other ends of the supportive struts are hooked to the movable hub. This forms an umbrella-like structure. By moving the movable hub along the center pole, the structure can be easily opened up or display or fold to save storage space. It could also form a multi-level structure and a number of variations. The lights can be hanged, or clipped to the structure. When the structure is implemented with hollow tubes, the lights can be inserted inside the tubes. The different styles of attaching lights to the supporting structure can be combined to achieve various desirable visual effects.
