“…In the traditional multi-area adequacy analysis, the interconnections are modelled as a support from the neighbouring power systems during the generation deficiency in the generation system of the concerned power systems [4][5][6]. In [11,13], the interconnections are modelled to transmit the shared capacity of jointly owned generators among the multi-area power systems and the interconnections are assumed to be adequate for the study.…”

“…Electric power utilities in many countries are operated as members of a largely interconnected power pool mainly because of the associated benefits, such as the reliability of supply, offered by the interconnections [4][5][6]. On the top of the existing transmission and distribution (T&D) network, a new grid namely 'supergrid' which will facilitate the connected utilities to share renewable energy resources has been elaborated in [7][8][9].…”

Wind is one of the fast growing renewable resources that can significantly contribute in achieving emission-free electricity generation system. Since wind resources are distributed across geographical locations, wind resource sharing among different geographical locations is essential to facilitate wind energy penetration and its full utilisation. A wind resource sharing strategy, for interconnected electricity networks, to achieve the national and regional renewable energy target is presented in this study. A multi-objective decision making problem has been formulated to optimally share the installed wind generation capacity in a multi-area power systems. Computational models have been developed for wind generation adequacy, emission reduction from wind energy and capacity upgrade requirements for tie-line interconnections. Trade-off analysis has been used to select the best wind resource sharing options. The proposed wind resource sharing strategy has been applied to the interconnected power systems operated within the National Electricity Market (NEM) framework of Southeast Australia to share the available wind resources within the geographical areas of the participating states in the NEM.

“…Billinton and Li [10,11] also developed new methods for multi-area generation system reliability evaluation considering load uncertainty, correlation between area loads, generating unit states and the supporting policy which is used in actual operation. Rau et al [12] talked about reliability of interconnected power systems and proposed a method for the calculation of the LOLP of two interconnected systems incorporating the correlation between demands using the bivariate Gram-Charlier expansion.…”

SUMMARYFast growth of large-scale distributed renewable energy resources, electric power markets, and responsive demand impose significant amount of correlated uncertainties on operation of the power system from both resource side and load side. Understanding the correlations between these uncertainties and applying sophisticated correlation analysis of multiple dependent uncertainties is a defining issue for the development of methodologies and technologies for power system operation in the new era.Application of correlation analysis in operation of the power system is not as fully explored as many other methodologies. The complexity of mathematic modeling of multiple correlated random variables challenges the power system professionals. The research is further challenged by lacking of operational experience and empirical investigation challenges.This paper provides a bibliography survey on application of correlation analysis in operation of the power system. The scope of the review covers IEEE power systems proceedings, IEEE and IEE transactions published after 1980. There are 77 relevant papers identified. These papers are put into seven technical categories: power system reliability, wind generation, power market analysis, load forecast, resource planning and dispatch, transmission load flow, other non-operation-related topics.

“…For two coupled networks the bivariate Gram-Chalier series, built from network cumulants, was utilized [5,6] to evaluate the .EEG, EEC, LOLP and EONS for each network. Numerical integration of the continuous surface PDF is needed before and after each unit commitment in both coupled networks [5,6].…”

An Improvement for the Outcome of the Cumulant Method in Two Coupled Networks

Over-estimations and/or under-estimations were recorded when utilization is made for the cumulant method in two coupled networks. The work of this paper is focused on the correlation between equivalent loads of the two networks. Correlation/uncorreclation of network loads directly affect the joint probability density function of network loads. Load uncorrelation is implemented. The results obtained for sampla networks strongly reinforced that the errors previously recorded for the cumulant method are attributed to the load correlation basis adopted. With uncorrelated network loads the outcome of this method is greatly improved.
