Martinez-Sanz I, Chaudhuri B, Strbac G, 2012, Impact of wind penetration and HVDC upgrades on stability of the GB transmission system
Several case studies are presented in this paper to better understand the impact of planned network changes on the dynamic stability of the future Great Britain transmission system. These studies have been conducted on a small network that is reasonably representative of the small signal stability problems present in the UK power system. The effect of wind penetration and HVDC links on the existing low frequency inter-area oscillations is analysed and interpreted for different possible future scenarios by observing the change of damping and frequency of this mode in response to these changes. © 2012 IEEE.

This paper presents an alternative approach topseudo measurement modeling in the context of distributionsystem state estimation (DSSE). In the proposed approach pseudomeasurements are generated from a few real measurements usingartificial neural networks (ANNs) in conjunction with typicalload profiles. The error associated with the generated pseudomeasurements is made suitable for use in the weighted leastsquares (WLS) state estimation by decomposition into severalcomponents through the Gaussian mixture model (GMM). Theeffect of ANN-based pseudo measurement modeling on thequality of state estimation is demonstrated on a 95-bus sectionof the U.K. generic distribution system (UKGDS) model

Introduction: Decarbonization of future electricity systems requires a significant proportion of electricity consumption to be supplied from nuclear, carbon capture and storage (CCS) plant and renewable sources. Since nuclear and CCS plant are less flexible than, for instance, natural gas-fired combined cycle plants, and renewable sources such as wind, solar and tidal are intermittent, this creates serious challenges to the way the current system is operated. In order to ensure that the system is capable of maintaining a supply and demand balance, the reduction in generation flexibility as a result of incorporating more low-carbon generation technologies has to be balanced with an increase in flexibility from demand. Consequently demand-side flexibility needs to be developed and smart domestic appliances can play an important role (IEA, 2008). In order to gain insight and understanding of the role and value of smart appliances, comprehensive studies of its economic value are required. Such analysis needs to consider relevant parameters such as consumers' behaviour and acceptance, appliance technology and future scenarios of power-system development regarding flexibility of generation and network capacity. This chapter presents a framework to assess the value of smart appliances, as flexible demand, to increase system flexibility and to provide new sources of ancillary services. The increased flexibility will improve system efficiency, reduce operating costs and carbon emissions, and increase utilization of renewable sources; from these benefits the value of smart appliances will be derived. However, any decrease in the value of energy services received as a result of, for instance, inconvenience caused by curtailment or rescheduling of consumption should, in theory, be deducted from such benefits. At the core of the framework is a model that simulates annual system operation, scheduling simultaneously generation and smart appliances, in order to minimize system oper

Moreno R, Pudjianto D, Strbac G, 2010, Future transmission network operation and design standards to support a low carbon electricity system
Increased connections of wind power in the Great Britain (GB) transmission system had triggered the need to review the fundamental principles behind the deterministic Great Britain Supply Quality and Security Standards (SQSS) that has been used for more than 5 decades. This review analyses the necessary upgrades to improve the efficiency of transmission system operation and capacity required to accommodate the present and future generation system. This paper in particular addresses a number of issues raised from the applications of deterministic SQSS and its operation and design efficiency concerning the best usage of N-k policy type. With respect to the United Kingdom (UK) transmission system operation, deterministic standards have been used to determine secure maximum levels of power transfers across a particular boundary. Our studies indicate that the deterministic standards are too conservative. This leads to over requirement of transmission capacity in planning timescales or significant constraints to access remote wind power in operational timescales. As an alternative, the use of an integrated reliability and cost-benefit framework to optimize the level of transmission system security has been developed. A wide range of studies have been carried out to analyze the benefits of this approach in the UK. The results indicate the need to move towards this integrated approach in order to maximize the value of transmission and to speed up the connections of wind power. ©2010 IEEE.
