“…This means that the proposed method allocates the losses by an average error less than 0.1% with respect to the centralized method. A comparison of results with the two already reported work in literature known as tracing method [9] and ITL method [7] is made in Table IV. For this study, 2 cases have been considered.…”

SUMMARYThis paper deals with the problem of transmission loss allocation in very large networks with multiple interconnected regions or countries. The main objective is to propose a method in order to identify the amount of losses that each participant in the market causes on all system areas. Transmission pricing of cross-border trades is often difficult since individual countries may use incompatible internal transmission pricing regimes, and they are usually unwilling to disclose any sensitive information about their own systems.This paper presents a new methodology based on the loss formula concept for allocating electric losses to generators and loads, participating in multiple interconnected energy markets. The only data required are the power flows and characteristics of tie-lines and PV Ward equivalent model of area networks from border nodes point of view. No information is required about individual loads, generations, or detailed internal networks. The methodology is illustrated on the IEEE 118 node network which is divided into three areas, each with a different internal transmission pricing methodology. The proposed methodology is shown to be simple, transparent and very fast, and it can deal effectively with multiple pricing regimes.

Interchanging power between power markets in multi area networks causes energy loss in tie lines and the cost of this loss should be allocated to separate areas. The responsibility of one power market for power losses in tie lines becomes worse due to sensitivity of separated power markets to share their networks detailed information with the others. This paper presents a methodology based on Z-bus loss allocation technique to deal with this problem by considering the PV Ward equivalent model of networks, cross border trade information and tie line characteristic as the main sources of information. So there is no need to access detailed information of one market for the others or central international operator (10). Numerical studies on the proposed method are performed on the standard 118 bus IEEE power system that is divided into three market areas and each area has its own regulation and pricing policy but exchanges power with others. The results show that this scheme is applicable in real systems and is reasonable compared with central loss allocation.

“…Em [16] é apresentado uma proposta para alocação de custos pelo uso da transmissão com o mé-todo EBE. No trabalho apresentado em [17] uma metodologia baseada no conceito de fatores de perdas incrementais na transmissão é apresentada para alocação de perdas elétricas para geradores e cargas, quando se considera vários mercados de energia interconectados. O trabalho apresentado em [18] propõe um algoritmo para alocação de custos de transmissão em um grande sistema de energia com base na abordagem do preço nodal com o esquema multiárea.…”

de Custos pelo Uso do Sistema de Transmissão em Sistemas Multiárea. Rio de Janeiro, 2014. 124p. Dissertação de Mestrado -Departamento de Engenharia Elétrica, Pontifícia Universidade Católica do Rio de Janeiro.Com o aumento das interligações elétricas entre países, surgiram vários desafios para reguladores e operadores do setor elétrico desses países. Um dos desafios mais importantes consiste em definir qual o custo pelo uso da transmissão de um país a outro país. O principal problema, neste caso, é que a informação elétrica de um país não está disponível para outros países, o que dificulta a devida alocação internacional pelo uso da transmissão. Este trabalho tem como objetivo analisar possíveis soluções para o problema da alocação de custos pelo uso da transmissão em sistemas multiárea. Para isso, alguns métodos representativos pelo uso da transmissão serão combinados com diferentes técnicas para criar sistemas elé-tricos equivalentes, representando um país (ou uma área). São analisados os mé-todos Pro-rata, divisão proporcional (PS-Proportional Sharing), Zbus e EBE (Equivalent Bilateral Exchange). Para gerar os equivalentes são considerados os seguintes modelos: equivalente baseado em uma rede otimizada equivalente (ROE), que cria linhas fictícias a partir das barras de fronteira de cada país e das tensões destas barras definidas no caso base; equivalente Ward, em que cada país estabelece seu sistema equivalente com o uso da técnica de fatoração da matriz de admitância nodal e; finalmente, o equivalente REI (Radial Equivalent Independent), no qual uma rede elétrica é reduzida a um equivalente radial. As análises dos métodos de alocação de custos pelo uso da transmissão junto aos sistemas equivalentes foram realizadas com os sistemas 9 barras e IEEE 24 barras, ambos com três áreas. Palavras-chaveAlocação de custos pelo uso da transmissão; sistemas equivalentes; sistemas multiárea. With the increase of the electrical interconnections among countries, there were several challenges for regulators and operators in these countries. One of the most important challenges is to define what is the transmission cost usage from one country to another country. The main problem in this case is due to the electrical information of one country which is not available to another country, which makes difficult the multiarea transmission cost allocation. The main objective of this dissertation is to examine possible solutions for the multiarea transmission cost allocation problem. To do this, some representative methods for transmission cost allocation will be combined with techniques to create equivalent electrical systems, which will represent a country (or area). The transmission cost allocation methods used are: methods Pro-rata, proportional sharing (PS), Zbus and EBE (Equivalent Bilateral Exchange). To generate the equivalents are considered the following models: equivalent based on an optimized network equivalent (ONE), which creates fictitious lines based on the optimization problem considering the interconnection buses of...
