This paper presents a method to estimate the amount of energy that can be shifted during demand response (DR) activation on domestic refrigerator. Though there are many methods for DR activation like load reduction, load shifting and onsite generation, the method under study is load shifting. Electric heating and cooling equipment like refrigerators, water heaters and space heaters and coolers are preferred for such DR activation because of their energy storing capacity. Accurate estimation of available regulating power and energy shift is important to understand the value of DR activation at any time. In this paper a novel method to estimate the available energy shift from domestic refrigerators with only two measurements, namely fridge cool chamber temperature and compressor power consumption is proposed, discussed and evaluated.

This paper presents an approach to develop power system transient stability assessment platform using equal area criterion for a multi-machine network based on multiple synchronized phasor measurement units (PMUs) and generator parameters. The Phasor measurement units used in this study have been developed in general hardware computers running on Linux operating system. A widespread open source software implementation of the Precision Time Protocol Daemon (PTPd) has been used to synchronise the phasor measurement units. The output data gathered from synchronised phasor measurement units is used offline for state estimation of the system and hence the estimated data was used for transient stability analysis by means of equal area criterion. An experimental setup has been built to evaluate the performance achievable with the proposed synchronisation solution of phasor measurement units for transient stability analysis of a multi-machine system.

Distributed solar photovoltaic panels (PV) installed on the roofs of domestic houses generate electricity from sunlight, which is important for both decarbonization and electricity bill reduction. This paper proposes a new control approach to enable high density solar PV generation to be connected to low voltage (LV) networks more efficiently by working closely with in-home battery. The charging and discharging periods are crucially important for improving the efficiency of the PV battery. An optimal control scheme for energy storage systems in LV networks is introduced to facilitate demand response (DR). The method described also regulates thermal violation and voltage violation caused by PV generation. Finally, the paper uses a five node LV network and typical household profiles to demonstrate the effectiveness of the proposed control strategy. The benefits in terms of load shift are shown under three different configurations by using a selected lithium-ion battery.

As a consequence of the fast development of renewable energy sources in the UK, higher transmission capacity will be required to integrate potentially large volumes of wind generation in the future. Also, over the next decade, maintaining the transmission system security and stability will become more difficult. A major increase in the application of HVDC transmission technology and the deployment of series compensation within the existing AC transmission system is expected to provide the required transfer capability in the future. However, there is also a need to employ smarter ways of operating these power flow control devices. Firstly, this paper investigates the capability of the HVDC link in improving the inter-area power oscillation damping. Two approaches in the design of power oscillation damping controller are demonstrated. Secondly, the paper presents the application of the HVDC links set-point adoption for the stability enhancement through a novel non-parametric control system design approach using the sample regulator control design method. This method is mainly attractive for applications in large integrated power systems since the controller design only requires knowledge of the nonparametric model of the power system i.e. the open-loop step response, which is easily obtainable compared to development of parametric model of the power system.

As the utilization of renewable energy sources (RES) and HVDC links is growing rapidly, many characteristics of the resulting power system can be seriously changed. HVDC links, as well as RES using converters as an interface with the main grid, can be all treated as non-synchronous sources. These sources are different from the traditional synchronous generators in many ways and bring significant challenges to the existing protection systems. Therefore, the aim of this paper is to explore power system protection performance issues under the context of the main characteristics of future power networks. In this paper the operating principles of converters is investigated. Initial equivalent models of Voltage Source Converters (VSC) in response to both symmetrical and unsymmetrical faults in the AC power systems are introduced and developed. Such models explain the characteristics of the future power networks with focuses on protection system performance. The VSC models will investigate system performance under fault conditions taking into account of European HVDC Grid Code requirements proposed by the European Network of Transmission System Operators for Electricity (ENTSO-E)[1].

The scalable communication, processing and storage of data within a power network is becoming more and more necessary to ensure the reliability of the grid and maintain the security of supply to consumers. Not all communications are performed in the same timeframe, at the same frequency, or at the same time of day; this results in problems when trying to coordinate a power network and the necessary data exchange. Different open or proprietary standards are often incompatible with each other both in terms of their communication protocols and data models. This causes electricity companies and standards groups to develop their own method of data exchange thus resulting in problems for exchanging and integrating this data, both internally and externally. Overcoming the challenges with incompatible data structure, serialisation formats and communication protocols will make it easier to integrate systems and realise the potential of being able to integrate data across domains. These include the ability to integrate real-time data into offline analysis tools; or utilising smart-meter data to enable true real-time pricing for electricity markets.

In this paper the authors propose an optimization solution of an installation producing electricity and thermal energy viewed as an energy hub that has as input parameters four types of primary energy (solar, wind, natural gas or biomass and diesel), while hub outputs are electricity and heating needed for a consumer. Also we can take into account the fact that the hub is interconnected with the electric power system (grid) which supplies electricity directly to the hub. The energy contains a wind turbine, photovoltaic panels, storage batteries, a DC-AC converter, a Stirling engine for cogeneration, and a diesel boiler.

Indonesia consists of many isolated electrical power system networks. Sumatera power system is one of the power system networks in Indonesia. It consists of 2 major networks, which are Northern Sumatera system and Central-Southern Sumatera system. Northern Sumatera system supplies two provinces, which are North Sumatera province and Aceh province. North Sumatera province has a loop topology while Aceh province has a radial one. In the last 3 years, there are four significant disturbances in the system that caused blackout situation in Aceh province. It caused so many complaints from customers and local government. The root cause of the problem came from the big power transfer along the radial topology and significant Force Outage Rate (FOR) along the transmission line. This situation was happened since more than 50% of power supply come from North Sumatera province and significant rate of lightning flash along the transmission line. This paper will give details about the implementation of No Load Shedding (NLS) Scheme in Aceh province network. With a a complete and smart combination with other special protection scheme, NLS scheme will increase reliability of electricity power supply to the local customer. This paper will explain the steps in designing the scheme, the need of coordination meeting with other stakeholder, and some constraints faced by the team in implementing NLS Scheme to the system. Finally, this paper will tell lesson learned in implementing NLS scheme and the benefit of this scheme to increase reliability of the system.

This paper introduces on a probabilistic model to automatically generate photovoltaic production profiles for a given geographical region and future scenarios for deployment of renewable energy resources. The model for these profiles uses local properties of buildings, demographic statistics, and historical weather data. Sub-models are calibrated with actual PV data from a smart grid pilot site in the Netherlands and literature based scenarios. It is shown that the model performs adequately and the results are compared with historical data of photovoltaic installations.

This paper describes the design and implementation of advanced Supervisory Power System Stability Controller (SPSSC) using Neuro-fuzzy system, and MATLAB S-function tool where the controller is taught from data generated by simulating the system for the optimal control regime. The controller is compared to a multi-band control system which is utilized to stabilize the system for different operating conditions. Simulation results show that the supervisory power system stability controller has produced better control action in stabilizing the system for conditions such as: normal, after disturbance in the electrical national grid as a result of changing of the plant capacity like renewable energy units, high load reduction or in the worst case of fault in operating the system, e.g. phase short circuit to ground. The new controller led to making the settling time and overshoot after disturbances proved to be lower which means that the system can reach to stability in the shortest time and with minimum disruption. Such behaviour will improve the quality of the provided power to the power grid.
