It uses market compatible game theory, graph theory, market mechanism, multilateral trade structure, etc. rather than conventional tools. The model is useful to emulate any active, competitive transmission sector. It has more relevance in countries like India with high T&D loss and power deficit problems. Cooperative game theory (CGT) is holistically applied in organizational, operational, commercial and planning aspects of restructure. A three phase CGT environment to model entity interactions, an elastic transmission service charge (TSC) to penalize abuse and a powerful power vector to resolve information asymmetry are some proposals developed in this context. In the scheme, Discos use power vectors to play the game and negotiate for agreeable TSC share and engineer fruitful mergers. A stable set of coalitions contracting optimal trades at lowest TSC is finally obtained. The method is illustrated on a 5 bus and successfully tested on a 24 bus Indian power system. The outcome is that agents aggregate sequentially, to safeguard network security as a common agenda, despite market activities starting at diverse locations. These results are important because transmission is the most difficult zone to model in electricity markets due to several issues and this model addresses most of them.

By use of the implemented solution, wind power can consequently be confronted to operational constraints related to high-powered thermal units, nuclear parks or cogeneration. Moreover, in order to optimize the large-scale integration of wind power production, the required reinforcements on a given electrical grid can also be evaluated on basis of the presented developments. The elaborated strategy can practically be applied to every kind of nonsequential Monte Carlo approach used to technically analyze a given transmission system. In the context of this work, the proposed solution has been implemented into the simulation tool Scanner# (property of Tractebel Engineering – Gaz de France – Suez company). Finally, in order to point out the efficiency and the usefulness of the proposed wind power model, the developed simulation tool has been firstly applied to an academic test system: the Roy Billinton test system (RBTS). Afterwards, in order to fully access the large offshore wind potential in the North Sea, the same tool has been used to evaluate the onshore reinforcements required in the Belgian transmission network.

Open access transmission brings new challenges to transmission network expansion planning. From the transmission corporation's view, the goal of optimal transmission network expansion planning scheme should not only bring the optimal transmission profit in the market, but also ensure high operation security and reliability, meanwhile social welfare is necessary to be accounted for. In this paper, the upper level programming considers transmission profit maximization in long-term planning, the lower level programming considers the social welfare maximization in short-term operation. Furthermore, N−1 security constraints are also considered in the model. A hybrid algorithm integrated with niche genetic algorithm (GA) and primal-dual interior method is adopted to solve the proposed bi-level programming model of the transmission network expansion planning. The planning methodology has been demonstrated on the 18-bus system to show the feasibility and validity, moreover, comparison has been made between traditional transmission expansion plan and proposed market-based transmission expansion plan; it was also applied to the real life system 77-bus system transmission grid.

Hosseinian","doi":"10.1002/ETEP.532","DOIUrl":"https://doi.org/10.1002/ETEP.532","url":null,"abstract":"Voltage Control Areas (VCAs) play an important role in voltage stability assessment and control. Since it is impossible to detect VCAs in real time during appearance of emergency cases for large-scale power systems, it is a reasonable solution to train and employ an artificial intelligent system (AIS), for on-line predicting of VCAs. However, at different emergency and alert cases, there are various VCAs for power system. Clustering the data of Participation Factors (PFs) of all studied cases into a finite number of groups would lead to a more accurate ANN-based online VCA identifier. Each cluster has a representative center that is the critical VCA corresponding to all contingencies and load stresses which would lead to the same cases as the members of that cluster. In this paper a novel data clustering method based on shuffled frog leaping algorithm (SFLA) is presented for this purpose. In the first part of present study the general application of SFLA in data clustering is compared with PSO as the most popular Memetic Algorithm (MA), to demonstrate the validity of proposed clustering method. Consequently, as the clustering of VCAs is a problem with linear equality constraint, the compatibility of SFLA for solving under constraint clustering problems and its priority to PSO from this point of view, are shown in this study. Numerical results are presented at the first part for three standard test data sets and at the second part for IEEE 118-bus test system.
