  • Distributed generation and energy storage System planning for a Distribution System Operator
    IET Renewable Power Generation, 2018
    Co-Authors: Zhao Xu, Yu Zheng, Dongxiao Wang, Zhao Yang Dong
    Abstract:

    The smart Distribution System architecture provides value-based control techniques that facilitate bi-directional power flows and energy transactions. Although consensus and understanding continue to develop around peer-to-peer transactions, a Distribution System Operator aims to promote and enable interoperability among entities, particularly those who own distributed energy resources such as energy storage System (ESS) and distributed generation (DG). In this study, the authors address the optimal allocation of ESS and DG in the smart Distribution System architecture, in order to help the integration of wind energy. The formulated objective is to minimise the sum of the annualised investment cost, the expected profit and the imbalance cost in the two-stage of power scheduling. The proposed model is verified on the modified IEEE 15-bus Distribution radial System. The simulation results have verified the proposed planning approach. Also, results show that a more risk-seeking operation strategy is recommended if wind power penetration increases.

  • impacts of large scale wind penetration on designing and operation of electric power Systems
    IEEE Transactions on Sustainable Energy, 2010
    Co-Authors: John Kabouris, F D Kanellos
    Abstract:

    Wind turbine technology has significantly improved over the last 20 years, allowing for the rapid growth of the wind penetration that we are now witnessing. Large-scale wind power penetration impacts the electricity supply industry (ESI) in many aspects and leads to fundamental changes in electric power Systems. Also, it raises a number of technical challenges for the transmission System Operator, Distribution System Operator, and wind turbine generator manufacturers. This paper aims to present in a thorough and coherent way the picture redrawn for electric power Systems under large wind power penetration. Topics related to technical challenges emerged and relevant technical solutions required are analyzed. Finally, general conclusions are extracted about the current and future ESI status and general directions are recommended.

  • a game theoretic analysis of transmission Distribution System Operator coordination
    European Journal of Operational Research, 2019
    Co-Authors: Helene Le Cadre, Ilyes Mezghani, Anthony Papavasiliou
    Abstract:

    Abstract In this paper, we formulate in a game-theoretic framework three coordination schemes for analyzing DSO-TSO interactions. This framework relies on a reformulation of the power flow equations by introducing linear mappings between the state and the decision variables. The first coordination scheme, used as a benchmark, is a co-optimization problem where an integrated market Operator activates jointly resources connected at transmission and Distribution levels. We formulate it as a standard constrained optimization problem. The second one, called shared balancing responsibility, assumes bounded rationality of TSO and DSOs which act simultaneously and is formulated as a non-cooperative game. The last one involves rational expectation from the DSOs which anticipate the clearing of the transmission market by the TSO, and is formulated as a Stackelberg game. For each coordination scheme, we determine conditions for existence and uniqueness of solutions. On a network instance from the NICTA NESTA test cases, we span the set of Generalized Nash Equilibria solutions of the decentralized coordination schemes. We determine that the decentralized coordination schemes are more profitable for the TSO and that rational expectations from the DSOs gives rise to a last-mover advantage for the TSO. Highest efficiency level is reached by the centralized co-optimization, followed very closely by the shared balancing responsibility. The mean social welfare is higher for the Stackelberg game than under shared balancing responsibility. Finally, under imperfect information, we check that the Price of Information, measured as the worst-case ratio of the optimal achievable social welfare with full information to the social welfare at an equilibrium with imperfect information, is a stepwise increasing function of the coefficient of variation of the TSO and reaches an upper bound.
