Distribution network will be no longer a passive termination of transmission network and the concept of active network has been recently introduced to indicate a new kind of distribution with DERs actively involved in system management and operation. Intentional islanding, i.e. the use of DG to supply portions (cells, microgrids) of distribution network during upstream line faults and scheduled interruptions, can be a valuable option to reduce the number of service interruptions. In the paper, an algorithm for the optimal allocation of automatic sectionalizing switching devices has been improved for the maximum exploitation of intentional islanding. Line faults and overloads have been considered as causes of interruptions. Stochastic models have been adopted to assess the probability of overloads and of properly functioning intentional islands. The application to real world case studies has highlighted the benefits achievable with intentional islanding as well as the inability of common reliability indexes (e.g. SAIFI, SAIDI) to properly perceive advantages that are inherently local.","PeriodicalId":427228,"journal":{"name":"2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies.

It plays an important role in maintaining system frequency and scheduled tie-line interchange power within specified domains. A new framework for forecasting and procuring AGC capacity so as to well balance the economic efficiency and system security in the competitive electricity market environment is presented in this paper. First, the load deviation percentage is obtained for each studied trading period based on historical data and used to make a preliminary estimation of AGC capacity requirement, and then a dynamic adjustment model is developed to refine the estimation by taking some relevant factors such as the control performance standard (CPS), units' regulation capabilities and load forecast errors into account. A procuring mechanism of the AGC capacity is next presented by trading off between penalties for tie-line power flow deviations and costs of AGC capacity procurement. Finally, a numerical example based on the historical data of Zhejiang provincial electricity market is served for demonstrating the essential features of the proposed model and method.","PeriodicalId":427228,"journal":{"name":"2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies.

A problem of the nose point of PV curve under an operating condition is formulated as the maximization of system loads with constraints corresponding to system operating conditions. A quadratic form with respect to state vector expresses the objective function. Network operating conditions are formulated by quadratic equations with respect to state vector in equality constraints. The problem of maximization of system load is formulated with an objective function and several number of equality constraints in power systems for the nose point of PV curve. The Lagrange's multiplier method is the most common method to the maximizing problem for the nose point of PV curve with the specified constraints for power system operating conditions. It is known that we can obtain the optimal point of the nonlinear programming problem is null point of the gradients of Lagrange function. The proposed method is composed of the Newton Raphson's iteration-procedure to find out the optimal point, where the Karush Kuhn Tucker condition is satisfied. Newton Raphson's technique has great advantages in fast quadratic convergence and less computer time. Numeric examples of the closest bifurcation, the nose point of PV curve and their applications are demonstrated with use of several model systems for the examination of proposed methods.","PeriodicalId":427228,"journal":{"name":"2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies.
