An Advanced Method of Congestion Management for Optimal Energy Pricing

As one of the electricity infrastructure, a robust power network is needed to support the sustainability of energy supply. Compared to other common customer goods, electric energy has some unique features that require specific consideration. Unlike most products, electricity cannot be stored in large amounts in an economical manner. Accordingly, electricity has to be simultaneously produced and distributed on demand. Transmission and distribution network systems are then used to deliver the power. The operating capability of generation, transmission and distribution systems must be adequate to meet the fluctuating demands of the customers. As illustrated in Figure 1, a simple configuration of an interconnected power system has basically three important parts, namely: generator as source of the electrical energy, transmission line for transmitting power to remote areas and the load which consumes the power.
