“…Penelitian ini mempertimbangkan perpindahan antara pemakaian dari grid dan sebaliknya, yaitu dari pemakaian pembangkit sendiri dalam perhitungan biaya wheeling. Komparasi biaya wheeling yang timbul pada transaksi di transmisi, pada tipe transaksi transmisi, dan pada metode perhitungan biaya transmisi, dideskripsikan pada [40].

Wheeling is a solution to the complexity of transmission network constructing problem. With the wheeling concept, a power plant owner can deliver electricity to its load without having to construct a transmission network. The owner of the power plant can utilize the transmission network belonging to other entities. The wheeling concept is an interesting thing in terms of increasing current renewable energy penetration. This is due to the construction of the transmission network, which is one of the obstacles in increasing renewable energy penetration. Fairness of wheeling costs is still one important topic. The discussion regarding wheeling costs emphasizes that the costs charged to each party involved can meet the fairness principle, which is in accordance with their respective contributions to the implementation of wheeling. Broadly speaking, research related to wheeling can be grouped into research for developing wheeling cost calculation methods and research for developing wheeling cost allocation methods. The development of the wheeling cost calculation method also includes the development of cost components that can be included in the cost calculation. This study summarizes the discussion of wheeling costs on three aspects, namely calculation methods, cost components, and cost allocation mechanisms.

“…However, the increasing penetration of DER at distribution level forces the need to adapt traditional cost allocation methods used in transmission system to the distribution level. In general, the cost allocation methods for transmission systems may be classified into three distinct categories: nodal marginal methods [3][4][5][6][7]; rolled-in methods [8][9][10][11]; embeddedmethods [12][13][14][15][16][17][18][19][20][21][22][23][24]. The cost allocation based on nodal marginal pricing for transmission systems is presented in [3][4][5], in which are considered the long-term and short-term marginal costs related to energy, reliability, investments and demand side.…”

a b s t r a c tThe high penetration of distributed energy resources (DER) in distribution networks and the competitive environment of electricity markets impose the use of new approaches in several domains. The network cost allocation, traditionally used in transmission networks, should be adapted and used in the distribution networks considering the specifications of the connected resources. The main goal is to develop a fairer methodology trying to distribute the distribution network use costs to all players which are using the network in each period. In this paper, a model considering different type of costs (fixed, losses, and congestion costs) is proposed comprising the use of a large set of DER, namely distributed generation (DG), demand response (DR) of direct load control type, energy storage systems (ESS), and electric vehicles with capability of discharging energy to the network, which is known as vehicle-to-grid (V2G). The proposed model includes three distinct phases of operation. The first phase of the model consists in an economic dispatch based on an AC optimal power flow (AC-OPF); in the second phase Kirschen's and Bialek's tracing algorithms are used and compared to evaluate the impact of each resource in the network. Finally, the MW-mile method is used in the third phase of the proposed model. A distribution network of 33 buses with large penetration of DER is used to illustrate the application of the proposed model.

“…According to [1], the objective of transmission pricing is to recover all or part of the existing and new cost of transmission system. In addition, pricing of transmission services plays a crucial role in determining whether providing transmission services is economically beneficial to both the wheeling utility and the wheeling customers.…”

Performance Evaluation of Embedded Transmission Tariff Models for Deregulated Electricity Market

During the regulated power system era, the three major components of the power system are treated as a single entity and managed by same firm. Electricity was then treated more as a welfare commodity based on political patronage. With the wide adoption of deregulation, which resulted in the wholesome privatization and commercialization of the generation and distribution components, the transmission facility was left in the hands of the Government. Considering that this is a sure link between the other two, there is greater need to develop a mechanism for its appropriate tariff determination in order to ensure fairness to all its users. A significant deficiency in its pricing is the non-inclusion of the reactive power component, which is seriously needed to ensure system stability. This work involved the performance evaluation of four embedded transmission pricing models. Based on the need to build-in payment for reactive power which is necessary to ensure system stability, further presents an improved postage stamp transmission tariff-pricing model that incorporates both real and reactive component of power. The Postage stamp method calculates all the network costs and divides it by the overall power transmitted through it. This single rate is charged to users irrespective of the source and destination of power transactions. This is a simpler, fairer and easier to implement approach for computation using Matlab and Excel Software packages. The proposed method gave average price of 29.48$/hr as against $27.75/hr when reactive power was not included for the South African 18-Bus System. This showed slight improvement when compared to the conventional approach where reactive power was not included in the power transaction. It may be applied in developing countries like Nigeria where Government is gradually pulling out of full funding of the power sector, and seeking for technically sound and financially buoyant local and foreign firms to take over significant part of the sector. The distance flow based and cost flow based methods showed very higher costs which may not be suitable for developing countries at their present stage of deregulation due to very low income per capita and low level of industrialization.
