  • the 2017 iso new england system Operational Analysis and renewable energy integration study soares
    Energy Reports, 2019
    Co-Authors: Aramazd Muzhikyan, Steffi O Muhanji, Galen Moynihan, Dakota J Thompson, Zachary M Berzolla, Amro M Farid
    Abstract:

    Abstract The bulk electric power system in New England is fundamentally changing. The representation of nuclear, coal and oil generation facilities is set to dramatically fall, and natural gas, wind and solar facilities will come to fill their place. The introduction of variable energy resources (VERs) like solar and wind, however, necessitates fundamental changes in the power grid’s dynamic operation. VER forecasts are uncertain, and their profiles are intermittent; thus requiring greater quantities of operating reserves. This paper describes the methodology and the key findings of the 2017 ISO New England System Operational Analysis and Renewable Energy Integration Study (SOARES). This study was commissioned by the ISO New England stakeholders to investigate the effect of several scenarios of varying generation mix on normal operating reserves. The project was conducted using the holistic assessment approach called the Electric Power Enterprise Control System (EPECS) simulator. The study finds a minimal impact on current normal operating conditions in the ISO-NE system for scenarios with relatively low penetration of VERs. Nevertheless, for scenarios with a significant presence of VERs, the system may require additional amounts of both upward and downward load following reserves and upward and downward ramping reserves to effectively maintain reliable operations. In these scenarios, the curtailment of semi-dispatchable resources also becomes an integral part of balancing performance; in part to complement operating reserves and in part to mitigate the topological limitations of the system. Indeed, the integration of significant amounts of VERs in relatively remote regions significantly increases the potential of congestion on several key interfaces. In many of these scenarios, the system experiences heavy saturations of regulation reserves and their increase would enhance the response to residual imbalances. The concludes with final insights into the emerging roles of curtailment, energy storage, and demand response as integral parts of normal balancing performance.

This paper describes the methodology and the key findings of the 2017 ISO New England System Operational Analysis and Renewable Energy Integration Study (SOARES). This study was commissioned by the ISO New England stakeholders to investigate the effect of several scenarios of varying generation mix on normal operating reserves. The project was conducted using the holistic assessment approach called the Electric Power Enterprise Control System (EPECS) simulator.The EPECS characterizes a power system in terms of the physical power grid and its multiple layers of control including commitment decisions, economic dispatch, and regulation services. This paper provides precise definitions of how variable energy resources and operating reserves are modeled. It also includes detailed models of the day-ahead resource scheduling, the same-day resource scheduling, the real-time balancing operations and the regulation service. Among the key findings, the reports shows that scenarios with high penetrations of VERs exhaust their operating reserves for part of the year and all scenarios curtail semi-dispatchable resources both to complement operating reserves and to mitigate some of the topological limitations of the system. Overall, curtailment emerges as a key balancing performance control lever and there is a clear need for higher amounts of operating reserves.

  • Operational characteristic Analysis of bipolar dc distribution system using hardware simulator
    The Transactions of the Korean Institute of Electrical Engineers, 2014
    Co-Authors: Jingyu Lee, Yoonseok Lee, Jaehyuk Kim, Byung-moon Han
    Abstract:

    This paper describes the Operational Analysis results of the bipolar DC distribution system coupled with the distributed generators. The energy management for AC/DC power trade and the Operational principle of distributed generators and energy storages were first analyzed by computer simulation with PSCAD/EMTDC software. After then a hardware simulator for the bipolar DC distribution system was built, which is composed of the grid-tied three-level inverter, battery storage, super-capacitor storage, and the voltage balancer. Various experiments with the hardware simulator were carried out to verify the operation of bipolar DC distribution system. The developed simulator has an upper-level controller which operates in connection with the controllers for each distributed generator and the battery energy storage based on CAN communication. The developed hardware simulator are possible to use in designing the bipolar DC distribution system and analyzing its performance experimentally.

    Abstract:

    This paper describes Operational Analysis results of the DC micro-grid using detailed model of distributed generation. Detailed model of wind power generation, photo-voltaic generation, fuel cells generation was implemented with the user-defined model of PSCAD/EMTDC software that is coded with C-language. The operation Analysis was carried out using PSCAD/EMTDC software, in which the power circuit is implemented by built-in model and the controller is modeled by user-defined model that is also coded with C-language. Various simulation results confirm that the DC micro-grid can operate without any problem in both the grid-tied mode and the islanded mode. The Operational Analysis result confirms that the DC micro-grid make it feasible to provide power to the load stably. And it can be utilized to develop an actual system design and building.

  • traffic micro simulation model for design and Operational Analysis of barrier toll stations
    Ain Shams Engineering Journal, 2017
    Co-Authors: Hassan T Abdelwahab
    Abstract:

    Abstract The objective of this paper was the development of a microscopic traffic simulation model for design, assessment, and Operational Analysis of toll stations. A simulation software using VB.NET was created to simulate the stochastic nature of traffic arrival, toll collection time, and driver decision making. The developed simulation model was used to analyze different scenarios of traffic volumes, toll booth capacity, driver types, and configuration of toll station. Results showed that volume per toll lane and method of payment significantly affect the average delay and maximum queue lengths of a toll station. Recommendations on number of toll booths are presented in order to process peak traffic hours without excessive delay times or long queues.
