Analysis of Complex, Multiple Electricity Markets

区域间的输电拥塞和不一致的市场规则会给消费者带来额外的成本，并危及互联电网的可靠性。有效的电网改进可以提高互联电网的传输能力，降低用户的拥塞成本。另一方面，不同的运营主体可能有不同的市场结构和规则，以清理能源市场和处理拥堵。如何处理单个市场内的拥堵，对邻近市场的电力流动和价格有重要影响。这一建议侧重于拥堵管理规则的经济分析和优化电网改善决策，以提高多个电力市场的社会福利。对不同区域间的交通拥堵管理协调规则进行比较，分析其社会成本和效益。我们还将探讨不同的拥堵管理方法如何影响市场参与者的战略行为，以及在具有多个市场的互联电网中单个市场的市场均衡。将应用全局优化技术来分析纳入大型非线性电力系统复杂特性的输电能力改进的经济价值。本研究的预期结果是改进电网决策以提高社会福利和有效的区域间市场协调以消除区域间能源交易障碍的系统方法。

Transmission congestion and inconsistent market rules between regions can impose additional costs to consumers and jeopardize the reliability of interconnected grids. Efficient grid improvement can enhance the transfer capability of the interconnected grids and reduce the congestion costs to consumers. On the other hand, different operation entities may have different market structures and rules to clear energy market and handle congestion. How congestion inside an individual market is handled has important consequences on power flows and prices in neighboring markets. This proposal is focused on the economic analysis of congestion management rules and the optimization of grid improvement decisions for social welfare enhancement in multiple electricity markets. Different inter-regional coordination of congestion management rules will be compared for the purpose of social cost and benefit analysis. We will also explore how different congestion management methods affect the strategic behaviors of the market participants and the market equilibrium of an individual market in interconnected grids with multiple markets. Global optimization techniques will be applied to analyze the economic value of transmission capacity improvements incorporating the complex characteristics of large-scale nonlinear power systems. The expected results of this research are systematic methods to improve grid decisions for enhancement of social welfare and efficient inter-regional market coordination to remove barriers of inter-regional energy trading.
