Abstract: A simulator models an energy and power system. The simulator allows a user to manipulate digital representations of nodes, which represent one or more components of power and energy assets. The simulator also allows a user to manipulate digital representations of edges, which connect the nodes, to form a power and energy network. A plurality of object classes correspond to the nodes and edges. The object classes comprise class inheritance structures so that constraints of a parent class are retained by one or more child classes. The interface on the simulator allows a user to model a power and energy system by allowing the user to connect the nodes with edges to construct a power and energy system, wherein the object classes for the nodes, when executed by the simulator, implement one or more dynamical models to model the power and energy assets.

Abstract: A computer-implemented method, data processing system and computer readable medium manages processing of data entries in a data buffer. Data entries are stored in a data buffer. A representation of a two-directional matrix is annotated to mark the data arrivals as a plurality of entries. In addition, the two-directional matrix is annotated to define a valid processing period for the data entries. The data entries in the data buffer are processed by removing the data entries from the data buffer, marked for processing in the two-dimensional matrix during the valid processing period, by annotating the matrix, labeled as ACS, to define the number of available entries as a cumulative sum along the columns, A-X, such that ACS=cumsum(A-X), where ‘cumsum’ is the cumulative column-sum. Finally, the data entries from the data buffer are processed to determine the entries removed from the data buffer as defined by the row-sum of X.
