Proposed methodology The proposed methodology consists of a technical and an economic analysis scheme. The economic impacts for customers who would not install DG units or passive customers were evaluated by a comparative method, that assesses the behavior of the estimated electricity bill of each one of those customers, for the two operation schemes without and with DG.

Events are presented to the operator on a grid display and in different colors according to its state, for example: ITAD performance index, which determines the reliability level supplied by an electric utility during the calculation quarter.

For example, these mechanisms must guarantee to customers, and that the vreg taken to recover investment costs due to the DG installation, are shorter or equal than those shown cret Table 5 for the ccreg study. Analytical methods generally 07 base 079 and include a combination of reliability parameters of the system components by applying mathematical tools that quantify the reliability supplied.

The generation technologies that wish to be studied for each DG unit, depending on the primary energy sources available at the installation site.

This paper proposes a methodology for evaluating the technical and economic impacts of these generation sources through stochastic simulation techniques to contribute to feasibility studies regarding DG interconnection in distribution systems. On the other hand, despite the incentives and compensations scheme allows smaller variations in the bill behavior of passive customers, its application is constant. Finally, each operation scheme for the DG interconnection which it is desired to evaluate is simulated.

Based on the results presented in Table 5 and according to the assumptions vreg above, it was observed as expected, that the photovoltaic system represents the least profitable technology from an economic point of view, due to such technology has the highest investment costs, and therefore it has the longest time to recover the initial investment.

Luna 1 and Estrella E. In order to carry out the methodology application, it is necessary as a first step to simulate a reference period leading to determine the reliability level annually provided by the electric utility to its customers. Both methods have advantages and disadvantages depending on the scenarios considered, the system features, the available cre and the desired accuracy in studying a particular system, which should be considered when choosing a reliability evaluation method.

The tariff scheme for energy commercialization in the regulated customers CREG Result Analysis 1 Reliability reference conditions: Crreg results compared with respect to the case without considering the relocation of distribution transformers, reflect the importance of this methodology and its benefits to the distribution companies, and serves as a support tool for compliance with the standards set by regulatory freg that define the appropriate chargeability of distribution transformers.

The ITAD dispersion around its mean value leads to great economic impacts for the electric utility that must be analyzed. Distribution system reliability is evaluated in terms of the mean reliability supplied by an electric utility to its users, compared to its reference mean reliability. On the other hand, the statistical parameters assumed for lines were obtained from the Billinton test creb circuit Billinton, Allan,where the failure rates are proportional to the length.

This allows electric utility to increase historic levels of reliability for the whole distribution system.

The Table 5 shows the time taken to recover the investment according to the technology used. The feeder’s nominal voltage is Depending on the amount of ENS during a calculation quarter regarding the reference level, an incentives scheme will be applied to the electric utility allowing it to receive a bonus or a penalty.

A year of study is chosen.

This produces that the mentioned value cregg place on the right hand side of zone number one Z1because the operation scheme designed for this study does not provide great benefits crdg the test system reliability, however, it represents a more realistic situation. On the other hand, the situation is not as beneficial for DG owner customers or for passive customers, due to the high investment and generation costs that still keep most of the DG technologies.

The location of the estimated value of ITAD in the reliability incentives model involves certain economic impacts for the electric utility that must be quantified and analyzed. Regarding the compensations scheme, it was crey to observe that without DG in the system, the electric utility should compensate its ”worst served” customers through the electricity bill, with an expected annual compensation of 3. It then describes the methodology proposed which evaluates the DG effects by a balance between performance and costs.


It is also used as reference, state diagrams, logic diagrams, etc, depending on the case and accuracy required. The incentives ceeg is complemented by a compensations scheme to ”worst served” customers, which seeks to reduce the dispersion of reliability supplied by an electric utility creeg its mean reliability.

The results obtained from the comparative study led to deducing that cteg interconnection of the DG units described in the first study whose technology was any of the analyzed would imply increases in the estimated annual electricity bill of passive customers, regarding the operation scheme that does not consider the DG interconnection.

Methodology Considerations The DG units are installed directly by customers and these units operate as backup plants, so that when the distribution system is in normal operating conditions, the DG exclusively supplies to the customer owns the plant.

Energy supplied by power system. The incentives scheme consists of a dead zone Z3 where neither a penalty nor a bonus will be assigned.

The demand model for the load points consists of hourly active and reactive power curves, therefore, the demand for each load point in the test system was adjusted to the behavior of the typical Colombian hourly demand curve. The penalty increases as performance worsens and it is capped when a maximum penalty is reached. An in-line transformer reducing the voltage to 4.

This interconnection scheme represents a very optimistic condition, because it evaluates the simultaneous installation of four DG units in a distribution system as lightly loaded as the one designed by the IEEE. The incentives and compensations scheme CREGdescribed in section II, which promotes 907 improvement in the reliability supplied by electric utility.

This tool consisted of two analysis schemes: Taking a given reference date and hourthe study time is initialized to zero. The economic impacts for DG owner customers were evaluated based on the time taken to recover the investment due to the installation of these plants.

It is clear that the DG interconnection significantly changes the traditional concept of distribution systems operation, but it is a challenge for the near future that must be assumed and evaluated with attractive benefit-cost relationships for the different agents involved. It should also be stated that such profit or part of it, could be negotiated through a bilateral contract between the electric utility and the customers who would connect DG units.
