  A strategy for voltage and reactive power control of an autonomous industrial power system including distributed generators and loads is presented. The investigation is based on time-domain simulations and aims to define the main functions for the power management system (PMS) that will govern the operation of the power system. Inter-bus transformers (IBTs) are used to limit the fault level but will affect the sharing of the total load reactive power between distributed generators. Generator AVR and on-load tap changing of the IBTs, both supervised by the PMS, are used together to regulate the local load voltages and at the same time to allow reactive power flow through the IBTs for the purpose of equalised sharing. A coordinated strategy is obtained. The knowledge gained from this study can be useful in future cases.

  An enhanced augmented Lagrangian Hopfield network (EALHN) for unit commitment (UC) is proposed. The EALHN is an augmented Lagrangian Hopfield network (ALHN) enhanced by unit classification to allow decommitment of excess spinning reserve units caused by the minimum up and down time constraints. First, the ALHN is used to solve the UC problem when neglecting the minimum up and down time constraints. Then, a heuristic-based algorithm is applied to satisfy the minimum up and down time constraints and decommit excess spinning reserve units. Finally, the economic dispatch problem is solved using an augmented Lagrangian-relaxation-based continuous Hopfield network (ALRHN). The EALHN is tested on several systems ranging from 10 to 100 units and compared to several methods. The total production costs from the proposed method are smaller those obtained using existing methods, especially for the large systems. Moreover, the computational times of the proposed method are also much faster than these for existing methods and slightly increase with the system size, which is very favourable for large-scale implementation.

  The transmission-grid system operator must maintain the system frequency of a synchronous transmission system within legislated tolerances. This task becomes of particular importance during large power imbalances. To establish a frequency-reserve scheme that maintains a healthy system frequency, the exact behaviour of generators and load response must be known. The paper provides details of load behaviour during a number of large infeed losses. These results show that the current load–frequency sensitivity factor of 2%MW/Hz is justified, and can even be extended to a value of 2.5%MW/Hz. Therefore, this value can be substituted in the calculation of reserve schemes on the electricity grid in Great Britain.
Unsynchronised two-terminal transmission-line fault-location without using line parameters

  The paper presents a new two-terminal transmission-line fault-location algorithm without requiring line parameters. The voltage and current measurements at both ends of a transmission line during a fault are assumed to be available and no synchronisation of the data is required. The proposed algorithm is suitable for estimating the location of asymmetric faults on a line when line parameters are not available. Evaluation studies using both simulated and field data are reported.

  An active islanding detection technique for an inverter-based distributed generator (DG) is presented. Two control strategies are studied: one in which the DG only supplies active power and one in which the DG supplies both active and reactive power to improve the power factor. The nondetection zone (NDZ) of the over/under voltage and frequency protection (OVP/UVP and OFP/UFP) method for each control strategy is determined. For the presented interface control, it is observed that the NDZ of the OVP/UVP and OFP/UFP is larger when the DG interface is designed to improve the power factor. In order to decrease the NDZ, an islanding detection method is designed that is based on creating a mismatch between the load and DG reactive power, thus forcing the frequency to deviate outside the OFP/UFP limits. It is shown that the proposed islanding detection technique is robust and has a negligible NDZ.
