| In order to achieve the goals of restructuring in the electricity market of Iran, the stock exchange was launched due to its proximity to the full competition market and the prices set close to the equilibrium market. The benefits of trading in energy stocks include more transparency of information and prices, faster price discovery, price fluctuations based on market and industry realities, higher market liquidity and financing for producers, supplying energy to distributors and consumers, allowing more control over deals and tracking offenses. In the Iran electricity market, transactions outside the market include the liquidity of transactions before the physical delivery of electricity on the day of operation; and the plants will not be fined in the event of non-delivery of the traded power on the day of operation. Therefore, to maintain national capital, the verification and feasibility of delivery of negotiable capacity on the day of operation by the independent operator of the system is mandatory. This paper examines the effect of the constraints and restrictions mentioned in the electricity grid, especially the fuel constraints on allocating the maximum allowable production capacity to power plants participating in the Energy Exchange. For this purpose, the objective function is defined in two levels, which is optimized by integrating the LP-metric algorithm with the sum of weight coefficients and converting it into a single-level problem in GAMS software. The proposed method is tested on the IEEE 24-bus network and the numerical results are analyzed. |
