Abstract/Summary 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.

Additional Notes This paper introduces schemes for incremental cost-based energy pricing model to deal with congestion including losses and transmission usage tariff, but simplify the method and have acceptable transparency so that it may correctly generate economic signal to the market participants. In this manuscript, a new scheme is presented to briefly review the main idea behind the LMP calculation, and further discuss the techniques used to incorporate transmission usage tariff into the model. This would be a comprehensive approach in which pricing of transmission service is implemented together with short-term nodal pricing or LMP, which represents energy price, network losses cost, and transmission congestion cost. Findings of this research are expected to be useful to support developing standard market design in transmission networks, which promotes economic efficiency, lowers delivered energy costs, maintains power system reliability and mitigates exercising market power.
