Power system analysis : emerging issues for utilities

K.R.W. Bell, C. Morgan

Research output: Contribution to journalArticlepeer-review


A number of factors are driving the provision of power system analysis tools in new directions. These include: growing uncertainties in the planning and operation of power systems; growing pressures in market-oriented industries for transparency and accountability in decision making; increasing need for exchange of data between different market players; and the entry of contemporary software technologies and numerical methods into the power industry. These pose opportunities and challenges to software providers. The position of a power system operator as an arbiter in market-oriented electricity supply industries means its decisions must be shown to be free from commercial bias. The separation of different power system services among many providers has led to an increasing need for exchange of data. This can lead to uncertainty regarding the accuracy of data, the management of which may require new tools. The cost and technology drivers, statistical and probabilistic methods, maintenance of legacy software and the nature of new facilities are discussed in the article.
