Power quality is one of the major requirements in power system operation and design. A power factor that is close to one is a good indicator for the overall power quality, especially for an electrical power system with high uptake of commercial loads with a large amount of inductance. A poor power factor normally leads to a less efficient electrical system, and may also be less economically efficient for system operators and end consumers. Therefore, power factor improvement plays a crucial role in the efficient system operation and electricity consumption costs reductions. This paper provides a detailed implementation of the technical and economic value of power factor improvement, and it is verified through an analysis of a real-world electrical system and loads. The efficiency of the method to determine the optimum location and size of capacitor installations to achieve desired goals is demonstrated in this experiment.

Steady state over-voltage is a bottleneck in distri-bution networks with high penetration of distributed generation (DG). This paper proposes a novel method based on linear programming (LP) to determine a very good approximation of the maximum DG penetration level in radial distribution networks. First, an analytical expression for maximum penetration level of one DG unit in a feeder is obtained. Then the feasible region for multiple DG units in a feeder is found. The proposed model is tested on two different grids, one of which is an agricultural feeder in Australia. The maximum penetration calculated by this model is compared with a comprehensive power flow method. The results confirm the accuracy of the proposed model. Finally, it is shown that increasing the number of DGs in a feeder may not increase the maximum penetration level.

Renewable energy generation based microgrids have significantly increased their share of total energy production in recent times, and this is now leading to major restructuring of traditional electrical grid infrastructures. One critical issue is the intermittency of the available power from renewable energy sources, which has made energy storage systems (ESSs) an important component for microgrids. A hydrogen based energy storage system, consisting of an electrolyser, a hydrogen storage tank and a fuel-cell, is particularly attractive in this context since it can directly store energy from PV sources. This paper now explores the possibility of utilizing the electrolyser of this system for fast response short term energy storage to help support momentary power imbalance within the microgrid. This avoids the extra cost incurred by using more conventional fast storage elements, such as batteries or supercapacitors, and thus offers a more sustainable approach for a microgrid system.

Optimal design of the hybrid power system (HPS) comprising wind turbines, solar arrays and battery storage is proposed in this paper. The main purpose is to develop an effective method for optimizing the size of HPSs considering reliability indices and power balance constraint. A new metaheuristic nature-inspired algorithm, called firefly algorithm (FA) is utilized to achieve these objectives. The results are compared with those obtained by alternative techniques proposed in the literature in order to show that the proposed algorithm is capable of yielding better optimal solutions. The simulation results show that the FA optimization method achieves better results than the alternative optimization methods.

This paper proposes a new control scheme for variable speed wind turbines with permanent magnet synchronous generators (VSWT-PMSG) based offshore wind farm (WF), which is connected to the main onshore grid through voltage source converter (VSC) based high voltage DC (HVDC) transmission system, to decrease the frequency fluctuations of the onshore grid. A centralized droop controller for VSWT-PMSGs is designed in order that the offshore WF can control the frequency oscillations of the main grid in which a large scale of WF composed of fixed speed wind turbines with squirrel cage induction generators (FSWT-SCIGs) is installed. In the proposed system, control of the frequency oscillations is performed by adopting the deloading operation. The simulation analysis is performed on a model system composed of synchronous generators (SGs), FSWT-SCIGs based WF, and VSWT-PMSGs based offshore WF to show the effectiveness of the proposed coordinated control system.

Residential demands are an important part of the overall electricity demand. There is a lack of research in community demand correlation, especially when PV penetration is high. This study devised a systematic approach to study the spatial and temporal correlation of high PV penetration community demand within residential neighbourhoods, with zone and regional demand. Results show residential demands in adjacent buses are highly correlated; however, demand changes at 1-minute intervals show little correlation, indicating a random nature of switching actions. The high PV penetration community demands are not highly correlated with zone or regional demand at present but trend lines indicate an increasing correlation between community demand and regional demand. Further, this study confirmed dry bulb temperature remained as an important factor for both peak demand and energy bill in the community of high PV penetration. This study helps improve the understanding of residential community demand characteristics and assists the management of peak demand and energy for community and distribution network.

Increased numbers of installed IoT devices and more complex building management algorithms make vital a secure, reliable, and cloud-based IoT platform, offering provisions for devices to communicate and react to predefined situations. This platform facilitates data acquisition, management, and interactions among IoT devices in order to exchange information including measurement data and control signals with controllers via a two-way communication mechanism. In this paper, an IoT platform to implement a device-supply management algorithm in a smart building, aiming to supply higher-priority devices from solar power and to maximize solar-power utilization, has been designed and implemented. Message Queue Telemetry Transport (MQTT), which is the state-of-the-art Internet of Things (IoT) protocol, has been adopted in this work to incorporate communications between the devices and the controller. MQTT publisher and subscriber are deployed in the Python programming language. A cloud-based data aggregation platform has been used with an interface to MATLAB, in which the device management algorithm runs. From the results, it could be observed that the IoT platform successfully achieves the goals of the designed device-supply management algorithm.

Renewable energy systems (RES) are increasingly popular due to depletion of natural sources. Optimal sizing oi hybrid RES is essential to permit a factual penetration of the renewable energy sources. Improper sizing might lead to increased establishment cost or Coptimal design configuration of standalone RES with battery storage using HOMER for a small community located in Portland, Victoria. To achieve that, a pre-feasibility study has been conducted. Sensitivity analysis has been performed for different values of hourly wind speed, solar irradiation, scaled annual average load and annual capacity shortage. Various renewable energy sources along with energy storage devices and their application are discussed in terms of cost and performance. The different solutions are analyzed and the optimum system configuration is selected. The characteristics of the optimally selected system are discussed.

This paper introduces a control technique for proportional load sharing in a DC microgrid during both islanded and utility connected modes. The DC microgrid is connected to a utility system through an interlinking voltage source converter and a unidirectional DC-DC converter. The DC-DC converter draws the desired amount of power from the utility, while the interlinking converter holds the DC bus voltage. The DERs in the DC microgrid are operated under droop sharing using DC-DC converters. Each DC-DC converter is equipped with a state feedback with integral controller that can regulate its output voltage for a wide range of input voltage fluctuation and load variation. Simulation studies are conducted on PSCAD/EMTDC to validate the proposal.

Over recent years, distributed energy resources (DER) have been the object of many studies, which recognise and establish their emerging role in the future of power systems. However, the implementation of many scenarios and mechanism are still challenging. This paper provides an overview of a local energy market and explores the approaches in which consumers and prosumers take part in this market. Therefore, the purpose of this paper is to review the benefits of local markets for users. This study assesses the performance of distributed and centralised trading mechanisms, comparing scenarios where the objective of the exchange may be based on individual or social welfare. Simulation results show the advantages of local markets and demonstrate the importance of advancing the understanding of local markets.
