SUMMARYA transmission restructure model is presented, which resolves line abuse, conflict of incentives and information asymmetry in electricity markets. 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.

“…Within the model we integrate a novel method based on graph theory, to spot the partners in the wide web that is the power system, who can cause counter-flows in the lines. This technique counters abuse of network due to selfish trade interests, information asymmetry, and decentralized decision structures resulting in uncertainties and instabilities [2][3][4]. The proposal is expected to trigger thoughts on increased efficiency and reduced electricity prices in markets via synergies of collaboration among Discos and competition between Gencos.…”

Modeling the transmission sector of electricity markets is a challenge, due to issues like violation of network operating limits, information asymmetry and conflict of incentives. In this paper we address all these concerns via an innovative method of amalgamating the Discos into coalitions so as to cause counter-flows in lines. The complexities of transmission operation are thus modeled in a Cooperative Game Theory environment. An intuitive method based on graph theory is then proposed to identify coalition partners among Discos who should rationally cooperate, to incur the minimum overall Transmission Service Charge. The technique is illustrated using a 24 bus real power system.

“…With several market players, cooperation is vital to reduce the above abuses of network, conflict of incentives and information asymmetry in a power market [9]. The VIU has no such organizational, operational, economics and planning issues [14]. But efficiency and managerial failures in VIU, and the need for a separate model for transmission sector in electricity markets, has opened a window of opportunity for applying several technologies to assert viability of transmission model.…”

Cooperative game theory is relevant for ensuring reliability of power grid of electricity markets, where central objectives of its transmission sector clash with the private incentive of its players. It is a critical component of market engineering as also is differential pricing, which is used here for pricing of transmission. Another tool used in the model for transmission sector, is a power vector to identify coalition partners. This procedural model is explained in three phases of game theory and is illustrated using a 24 bus power system. The results are significant and show that loss, congestion and total power flow in lines decrease considerably, improving efficiency.
