This is because the price that could be negotiated between the customer and the electric utility, to improve the reliability, does not cover the additional investment that the customer would do by the purchase of additional generation capacity used as backup for the system. These impacts are discussed in the next section IV-C4.
This impacts assessment allows through a balance between cdeg and costs, contribute to feasibility studies to connect these sources.
Services on Demand Article. Next, the assessment periods of the reliability supplied by electric utility to its customers were simulated. It can thus be deduced that the utility would be perceiving an annual profit, exclusively from applying the incentives and compensations scheme. This information is accumulated in an historic database for further analysis and for reporting. Current and historic system reliability international indicators e.
This is because, despite the CU dg allows a greater variation in the bill behavior of passive customers, the application period is very short, because the DG units operate as backup plants to fault conditions in the system.

The characteristics of the DG units considered in each of these schemes are shown in Table 1. On the other hand, the results obtained from the comparative study led to deducing that the interconnection of the DG units described in the second study whose technology was any of those analyzed, would imply decreases in the estimated annual electricity bill of most of passive customers, with respect to the operation scheme that does not consider the DG interconnection.
For this application case, the distribution system does not consider the two in-line regulators, the in-line transformer and the shunt capacitors. It was considered that the period of useful life of a DG plant corresponds to 20 years, regardless of the technology type used. Unbalanced loading with both ”spot” and ”distributed” loads. The methodology was adapted for its application to the Colombian regulatory conditions related to: An in-line transformer reducing the voltage to 4.
The location of DG units in the system customers. Luna 1 and Estrella E. The remaining amount of such ENS is going to continue appearing and it will be evaluated with the same RC.
However, this study assumes that the capacities of the DG plants adequately represent the peak demand of the respective plant owner customers, which is a more realistic situation. For simulating the first assessment period, the iterative simulation procedure was applied for the same operation scheme without DG which was executed for years of analysis.
Finally, each operation scheme for the DG interconnection which it is desired to evaluate is simulated. This situation has led to implement the concept of small generating units located near to consumption points, incorporating the electrical system backup, as an option of great penetration in the electric sector commonly known as distributed generation DG.

The proposed methodology was applied to the IEEE 34 node test feeder, from which it was concluded that the technical benefits of DG interconnection in distribution systems are very significant for both the electric utility and its customers.

The penalty increases as performance worsens and it is capped when a maximum penalty is reached. In OMS, the network map is geographically visualized.
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. The system registers the time dedicated to an event, the type of event, employed human resources and materials. This module helps the operator with assigning a crew to an event outage caseand dispatch with a work order; initially to inspect, then to repair the fault or carry out maintenance.
Regarding the compensations scheme, it was possible 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. This is mainly due to the CUdg is higher or lower than the RC respectively.
Very long and lightly loaded. Events are presented to the operator on a grid display and in different colors according to its state, for example: Evaluating and comparing the electricity bill of each customer, for the two operation schemes with and without DG. It is important to indicate that the photovoltaic system is the only technology whose application not only increases the electricity bill of passive customers due to the implementation of the incentives and compensations scheme, but also because its CU dg is higher than the RC.
According to all the results presented above, it was thus concluded that it is more profitable for a customer to install DG whose capacity represents its actual peak demand or its projected demand. Once the key analysis described above was understood, it was evaluated the results of the comparative study. To check the validity of the methodology, a real distribution system belonging to an electric utility in Colombia is used, which takes into account both single and three phase distribution transformers.
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. Analytical methods generally involve base conditions and include a combination of reliability parameters of the system components by applying mathematical tools that quantify the reliability supplied.
For simulating each of these periods, the iterative simulation procedure for years of analysis was applied. National University of Colombia. These impacts result from implementing the compensations scheme to ”worst served” customers and they are discussed in the next section IV-C4. It was also concluded that the economic benefits of connect DG plants are directly for electric utility, because it is the one that perceives profits with the implementation of the incentives and compensations scheme due to the reliability supplied.
It is also used as reference, state diagrams, logic xreg, etc, depending on the case and accuracy required. CandidateNational University of Colombia, luisluna84 gmail. In order to carry out the implementation of this study, it was necessary as a first step to bring up a simple key analysis for evaluating the results of the comparative method, which is shown in Figure 7.
