This study assesses the potential impact of high renewable generation on the spot electricity prices, generator revenue and profits in an energy-only electricity market. In particular, it presents modelling outcomes for the Australian National Electricity Market (NEM) with a range of possible renewable penetrations in 2030. It is assumed that the current reliability standard is maintained and participants...
Increasing variable renewable generation penetrations will cause increased cycling operation for conventional generating plants. Not all of these plants are necessarily well suited to such operation. Traditional long-term generation planning frameworks often neglect these operational characteristics and therefore do not reflect the operational constraints and costs associated with cycling of generating...
A method is developed to explore the potential links between an oligopolistic electricity market and a competitive emission permit market in which permits allocated to those highly efficient generation companies (units) with lower emissions could be traded to other companies with higher emissions. The well-developed Cournot non-cooperative game model is employed to describe the behavior of power producers,...
Transmission congestion occurs more frequently in deregulated power systems, and congestion management has become a major issue in modern power system operation under the emerging electricity market environment. In many operating electricity markets, a hybrid trading mode with pool and bilateral-contract trade inclusive is employed. Coupling exists between these two kinds of trade as both are implemented...
The research work presented in this paper represents a step forward with respect to previous approaches in the field of electricity market operating performance evaluation in China. A new method for the comprehensive evaluation of electricity markets is presented through the combined use of the fuzzy set theory and analytic hierarchy process (AHP). The fuzzy set approach is employed to identify the...
Generation plant efficiency is an important measure for evaluating the operating behavior of a power plant, and hence an issue of extensive concern with generation companies. On the other hand, in the deregulated electricity market environment, the change of generation efficiency before and after the restructuring is a very important index for evaluating, at least to some extent, if the restructuring...
A stochastic optimization approach is proposed for the unit commitment problem with the uncertainty of wind power generation taken into account, based on mixed-integer linear programming (MILP). The problem is formulated to minimize the total operation cost of thermal units. In considering wind power generation, scenarios are generated by Latin hypercube sampling (LHS) and the stochastic optimization...
The employment of energy-saving dispatching could reduce energy consumption and pollution emissions. The State Development and Reform Commission of China issued the policy of energy-saving generation dispatching, and it is expected that this dispatching scheme will be implemented in China soon. In this dispatching scheme, the ranking of generation dispatching will be based on the energy consumption...
This paper proposes a stochastic approach based on Monte-Carlo Simulation (MCS) to account for various uncertainties when determining the overall generation cost of electricity generation portfolios. This approach extends the traditional deterministic methods for solving optimal generation mix by incorporating uncertainty into key cost assumptions and therefore solving the probability distribution...
Interruptible loads are consumers who agree to be interrupted, or whose consumption may be reduced by the utility, in order to maintain system security or to reduce market prices. Incorporating interruptible loads in day-ahead markets could maximize their potential in providing ancillary services because it enables them to plan their operations, and for them to offer reliable curtailment capacities...
There is growing world-wide and Australian interest in the greater potential role of distributed generation and demand-side resources within the electricity industry. These distributed resources can offer promising economic and environmental benefits for power system operation. There are considerable challenges, however, in developing modelling tools that can explore the operational value of such...
This paper focuses on nuclear power's application to electricity generation, noting that its military and foreign policy implications cannot be ignored and thus must be considered. We first set out a sustainability framework for assessing electricity industry design options and discuss the key issues for nuclear power in this context. We then review nuclear power's troubled past and contested present...
The paper discusses how electricity distributors are in an excellent position to provide a range of RAPS services to remote area customers. However, there are a variety of barriers to their involvement. In NSW these include unfamiliarity with RAPS technology, differences in the nature, timing and proportion of costs involved with RAPS and grid supply.
