The real-world performance of inverters is investigated across their full range of operation, concentrating on harmonic distortion and power factor. The inverters under review are representative of a cross-section of the UK market in terms of price and device quality. They include both voltage and current source converter topologies. The test results are compared against the relevant clauses of the BS EN 61000-3-2 standard for electromagnetic compatibility and those of Engineering Recommendation G83/1, for the UK. The additional impact of DC coupled energy storage on one system is considered. The implications of part-load performance are evaluated. Concerns are raised regarding the ongoing applicability of prevailing standards within future networks in which high penetrations of inverter-interfaced distributed generation are prevalent.

Developments in energy storage technology will start to play a prominent role in overcoming the problems of generation intermittency by providing the ability to shift demand to times when generation is available. However, exploiting the potential of this technology requires the design of an optimal charging and discharging schedule to allow its integration with the energy network that brings maximum advantage to both the system and the user. This paper introduces a mathematical model for generation and demand forecasting with energy storage scheduling that can be used for micro-grid and small power park applications. The proposed solution models the physical limitations associated with the energy storage technology used, which will constrain charge and discharge schedules beyond what can be forecast for them. A case study of a community feeder with large PV installations is presented to demonstrate the effectiveness of the model. Day-ahead charge and discharge schedules were produced that increased self-consumption within the system and reduced energy export to the grid. The main contribution of this work is the design of a generic parametrized forecasting and energy storage scheduling tool that will be a platform for further development to specialized storage technology and its potential scalability.

The electrification of heat and transport along with significant increases in distributed energy resources pose challenges for distribution network operators (DNOs) as they evolve into distribution system operators (DSOs). Issues may include capacity constraints, voltage excursions, lower supply security and reduced power quality. A method of addressing these matters whilst unlocking capacity is therefore required. This paper will outline the case for the selective interconnection of grid supply points and primary substations via fully controllable power electronic links. This interconnection would form the basis of a ‘power levelling’ network to help alleviate the above concerns as an alternative to a conventional ‘more copper’ reinforcement strategy. Power flows for a conventional network will be benchmarked before assessing the potential capacity release created by delivering energy from multiple substations via controllable interconnection. Medium voltage direct current (MVDC) networks (operating in the range of 5–50 kV) represent a candidate technology for the proposed interconnection. The paper reviews current technology readiness level, international learning and relevant knowledge from other power sectors.

This paper illustrates the risk assessment on electricity price forecast uncertainty. The high-risk periods under different time have been indicated. Autoregressive integrated moving average (ARIMA) models and artificial neural network (ANN) techniques are introduced to forecast electricity prices in UK electricity market. Also, this paper investigates the risk index of electricity prices due to forecast uncertainties in the competitive power market through two aspects — daily and seasonal. This risk index is calculated using the errors of short-term electricity price forecast. The input data of forecasting models is divided into weekday and weekend profiles and this is done to observe the different electricity price dynamic risks between weekdays and weekends.

This paper will review the recent and on-going changes to the power system in Great Britain (GB). One of the main challenges resulting from these changes in generation mix is the assurance of frequency stability in a low inertia system, and the provision of adequate dynamic responses to frequency changes, while meeting the requirements of the energy trilemma. Specifically, the increase in penetration of non-synchronous generation increases the risk of undesired operation of protection devices and contributes to a shortage of dynamic immediate response to frequency changes. A range of potential solutions will be briefly reviewed in this paper including, demand side response (DSR), energy storage, synthetic inertia, and synchronous condensers. A case study concerned with evaluating the impact that synchronous compensation may have in a low inertia power system will be described in the paper. The paper will conclude with an outline of the avenues for further study towards addressing the challenge of frequency stability and system inertia in a future power system.

Distribution System Operators (DSO's) in the Netherlands are generally more focused on Medium Voltage (MV) grids than on Low Voltage (LV) grids as higher voltage levels contribute more to the SAIDI. However increasing interruption times, increasing costs and the energy transition on LV level encourage the DSO's to focus on LV grids as well. A first step is the investigation of failures in LV grid components. In this paper a literature review on this topic is presented and the outcomes are discussed. It is concluded that the method of modelling of ageing components on MV level cannot be applied to LV level because of the absence of temperature-related and electric stresses in LV components. In addition the possibilities for diagnostics are limited due to attenuation of electric signals. Although statistical methods are currently used for condition assessment of distribution grids, the LV level remains partly unspoilt terrain. However there remain some challenges related to data availability and quality. The use of statistical methods is investigated in further research in order to be able to perform condition assessment on LV level.

As part of the transition from distribution network operator to distribution system operator (DSO), decentralised pricing of energy is an area that needs to be considered. This paper considers different roles for the DSO in facilitating distributed markets including the decentralised and centralised approaches. The latest work in distributed markets has been reviewed including two major pilot projects involving DSO type operation of distribution markets. The use of distribution locational marginal prices (DLMPs) in distributed markets has been studied as a promising means of directing investment and managing constraints in distribution systems. Some simple case studies involving DLMPs in an example distribution network were modelled using Matpower and it was seen that marginal prices could result in reduced losses and congestion if DLMPs are passed on to distributed energy resources. A case was considered of a bus with losses resulting in DLMPs 6% above the grid import cost and it was seen if the DLMP market was used a generator installed at this bus could reduce the cost of losses by up to 14%.

The aim of this paper is to describe an exploratory study using an action research approach to improve student work based distance learners' independent research skills through an industrial project to increase their value to their employer. Students undertake a 20 credit industrial project with the key aim to develop on taught material and undertake independent research within the context of the work place. Although there were some good projects each year, a number of projects were not helping the students reach their full potential or adding value to their respective company's business. The ‘action research’ approach helped identify issues and put in place a number of remedial solutions as described in this paper.

The UK electrical power network is currently transitioning towards a ‘smart grid’. This will be driven by the take up of green devices such as electric vehicle charging units, solar generation and district heating schemes. In order for Distribution Network Operators (DNO) in the UK to balance supply and demand they will need to maximise utilisation of existing assets under challenging conditions. This paper details a Finite Element Magnetic Method (FEMM) model used to simulate the thermal impact on cable insulation asset lifespan for two unique aspects; the non-standard burial of adjacent Low Voltage (LV) electrical power cables on high voltage (HV) electrical power cables; and a typical district heating scheme. Principle results have shown a conductor temperature rise of 14 oC in HV cables under non-standard LV cable burial conditions, which could result in significant deterioration in cable lifespan. The introduction of a district heating scheme indicates a HV conductor temperature rise of 4.5 oC, which is close to the manufacturer's insulation deterioration tolerance.

This paper proposes the Self-learning Cuckoo search algorithm to solve Multi-Area Economic Dispatch problems. The main objective of multi-area economic dispatch is to minimize the total fuel cost while satisfying balanced-power constraint in each area and limitations of generators and transmission lines. In addition, the proposed method is an improvement of the Cuckoo search algorithm with a new strategy to enhance Cuckoo eggs. The Cuckoo eggs will learn together to give the better solutions. The proposed method has been evaluated on two case studies of MAED to investigate the efficiency. Numerical results show that the proposed method is better than the conventional Cuckoo search algorithm and other methods in literature. However, in large-scale system, the computational time is slower than other methods.
