Abstract: In this paper, a two-dimensional Cournot model is proposed to study generation companies’ (GENCO’s) strategic quantity-setting behaviors in the newly established Yunnan’s electricity market. A hybrid pricing mechanism is introduced to Yunnan’s electricity market with the aim to stimulate electricity demand. Market equilibrium is obtained by iteratively solving each GENCO’s profit maxi...

Electricity market mechanisms designed to steer sustainable generation of electricity play an important role for the energy transition intended to mitigate climate change. One of the major problems is to complement volatile renewable energy sources by operationally flexible capacity reserves. In this paper a proposal is given to determine prices on electricity markets taking into account the op...

Two basic market designs are used for the trading of electricity in meshed electricity networks with transmission constraints. Analytical results show that, in two-node networks, a market design integrating transmission and energy markets reduces the ability of electricity generators to exercise market power, relative to a design with separated markets for transmission and energy designs. In mu...

The wave of electricity market restructuring both within the United States and worldwide has brought the issue of horizontal market power to the forefront. Traditionally, estimation and prediction of market power has relied heavily on concentration measures. In this paper, we discuss the weaknesses of concentration measures as a viable measure of market power in the electricity industry, and we...

The electricity market restructuring, and its worldwide evolution into regional and even continental scales, along with the increasing necessity for an adequate integration of renewable energy sources, is resulting in a rising complexity in power systems operation. Several power system simulators have been developed in recent years with the purpose of helping operators, regulators, and involved...

This mathematical model allows calculation of Unit Commitment (hereinafter UC), providing for compliance with all technical limitations in the equipment state and electricity regime parameters to ensure the minimization of the total cost of electric power generation, as determined on the basis of notifications wholesale market participants on the composition and parameters of the generating equ...

Several demand response (DR) strategies rely on real-time pricing and selfish local optimization, which may not result in optimal electricity consumption patterns from the viewpoint of an energy supplier or a power system. Thus, this paper proposes a strategy enabling centralized adjustments to cost-minimize consumers’ load. By employing the strategy, an aggregator is able to alter electricity ...

In open electricity market, electricity purchasers will trade in two different ways of marketing. Contract and power auction market, a typical decisionmaking is how to determine purchasing proportion of two markets to reduce purchase expenses and avoid risks. Based on chance-constrained programming, a new purchase decision-making optimization model with stochastic constraint of Distribution Com...

In this paper, we analyze Nash equilibria between electricity producers selling their production on an electricity market and buying CO2 emission allowances on an auction carbon market. The producers’ strategies integrate the coupling of the two markets via the cost functions of the electricity production. We set out a clear Nash equilibrium on the power market that can be used to compute equil...
