The Brazilian cost-based market employs the single-settlement system to clear electricity. Besides single, this system adopts a hybrid mechanism in which the amount of electricity measured during production and consumption in the real-time market is cleared with the electricity price set during the operation's schedule in the day-ahead market. The result is that the intersection between demand and supply does not set the electricity price neither in the day-ahead market nor in the real-time market. This work studies the flaws of the Brazilian settlement system. The study demonstrates that the two-settlement system is a better option for this market because it prices the electricity correctly at the moment of production and consumption, encourages the market participants to furnish accurate data for the system operation, mitigates anti-competitive practices, and induces market efficiency.

巴西基于成本的市场采用单一结算系统来清除电力。该系统除采用单一机制外，还采用了一种混合机制，即通过在日间市场的运营计划中设置的电价来清除实时市场在生产和消耗过程中测得的电量。结果是供需之间的交集既不会在日间市场中也不会在实时市场中设定电价。这项工作研究了巴西定居系统的缺陷。这项研究表明，对于这种市场，双结算系统是一个更好的选择，因为它可以在生产和消费时正确地对电价进行定价，鼓励市场参与者为系统运行提供准确的数据，
