CREG 097 PDF

Dum Based on the results of the incentives scheme shown in Table 4, it was possible to observe that without DG in the system, the electric utility neither receives financial benefits nor should pay financial penalties, because it is located in the dead zone of the incentives curve. This reference period led to determining among others, the dead zone for the incentives scheme that is shown in Figure 5. Distribution Modeling 1. These indexes allow assessing the distribution system reliability and the ITAD index. Such rules were defined in an incentives and compensations scheme aimed at stimulating the ongoing improvement of reliability. The incentives and compensations scheme CREGdescribed in section II, which promotes the improvement in the reliability supplied by electric utility.

Mikabei On the other hand, the following variables are calculated: Creeg the absence of an existing event, the system creates a new one. 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.

Crdg 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.

These results allow through a balance between performance and costs, contribute to feasibility studies for DG interconnection in customer installations. Result Analysis Once the simulation of both the reference period and the assessment periods has been completed, the following analysis is made: As a conclusion of the incentives and compensations scheme due to the reliability supplied, it should be noted that without DG the electric utility is leaving to receive an expected annual value of 3.

After, two assessment periods were simulated which considered different operation schemes for the DG interconnection in the test system. The first study implies the simultaneous installation of four DG units, located in the test system customers with the highest electricity consumption.

The simulation procedure described above is presented cgeg a flowchart Figure 2 B. The simulation procedure described above is presented on a flowchart in Figure 2. If reliability is worse than the dead zone boundary Z2a penalty is assessed. Based on the results of technical impacts for system that bring the application of each study, it was possible to analyze the estimated impacts on the incentives and compensations scheme.

The methodology was adapted for its application to the Colombian regulatory conditions related to: This is because if the reliability became greatly improved, then passive customers would prefer not to have the electricity, because the electricity unit cost would be higher than the cost they are able to pay, that is the rationing cost. Studying and comparing the incentives and compensation due to the reliability supplied, for the two operation schemes with and without DG.

In order to carry out the implementation of the comparative method, it was required the information of the values of CU dg according to the technology used, without considering the incentives and compensations scheme due to the reliability supplied. Such rules were defined in an incentives and compensations scheme aimed at stimulating the ongoing improvement of reliability. These indexes allow assessing the distribution system reliability and the ITAD index.

Luna 1 and Estrella E. For each scheme, it is necessary to model the distribution system considering three variables: The incentives scheme consists of a dead zone Z3 where neither a penalty nor a bonus will be assigned.

How to cite this article. 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.

Tracing options allow the operator to visualize the upstream connectivity, downstream and between two points. Such mean reliabilities are expressed as the following indexes: Methodology for assessing the impacts of distributed generation interconnection. For example, these mechanisms must guarantee to customers, and that the times taken to recover investment costs due to the DG installation, are shorter or equal than those shown in Table 5 for the second study.

For each scheme, it is necessary to model the distribution system considering three variables:. If reliability is better than the dead zone boundary Z1a bonus is given. 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.

This information is presented in Table 6. For the application of these studies that consider the DG interconnection, it was necessary to define the generation technologies to be analyzed for these plants which corresponded to renewable sources, and they are presented below:.

The results presented in Table 5 were evaluated with the following two assumptions:. This allows electric utility to increase historic levels of reliability for the whole distribution system.

These impacts are discussed in the vreg section IV-C4. The generation technologies that wish to be studied for each DG unit, depending on the primary energy sources available at the installation site. Taking a given reference date and hourthe study time is initialized to zero. 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.

This information is accumulated in an historic database for further analysis and for reporting. Related Articles

Tuk This impacts assessment allows through a balance between performance and costs, contribute to feasibility studies to connect these sources. Once the key analysis described above was understood, it was evaluated the results of the comparative study. This information is presented in Table 6. However, if the utility has historical information about its reliability behavior, then this step is unnecessary.

Vigul resolucion creg de pdf files — PDF Files 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. 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. This is because the application of the incentives and compensations scheme would cause some increases in the electricity bill of passive customers, which would be higher than the reductions in the bill due to the CU dg in most of the technologies is lower than the RC. Considering an n-1 contingency level and assuming that the system is operating normally, it is generated for each system components a random number between 0 and 1 from a uniform distribution for that range. Finally, each operation scheme for the DG interconnection which it is desired to evaluate is simulated. These results allow through a balance between performance and costs, contribute to feasibility studies for DG interconnection in customer installations.
