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. These guidelines consist in that the simulation time increases at irregular intervals, and the use of hourly demand curves for each customer.

On the other hand, the following variables are calculated: 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. The ITAD reliability index and the incentives and compensations scheme adopted in the methodology are not evaluated quarterly as described in section II, but annually.

Reliability techniques can be based on analytical methods or simulation methods Billinton, Jonnavithula, However, when DG units are connected, a large cteg of the ENS will be supplied by the new generation sources interconnected to the system and it will be billed to customers through the unit cost of electricity service from DG units CU dg. For simulating each of these periods, the iterative simulation procedure for years of analysis was applied.

It was considered that the period of useful life of a DG plant corresponds to 20 years, regardless of the technology type used. CandidateNational University of Colombia, luisluna84 gmail.

Services on Demand Article. Current and historic system cref international indicators e. The proposed methodology consists of a technical and an economic analysis scheme. The simulation technique used corresponds to Monte Carlo sequential of mixed time Billinton, Jonnavithula,therefore the methodology designed was adapted to the guidelines proposed by this technique. The estimated values of the unit cost of electricity service described in Table 6 were the same for all passive customers, because these customers were connected to the same voltage level.

Creg Alexandra Rico — This module helps the operator with assigning a crew to an cregg outage caseand dispatch with a work order; initially to inspect, then to repair the fault or carry out maintenance. 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: Introduction Due to growing demand and concern over environmental pollution, new electricity generation with technological alternatives having the lowest impact on the environment is becoming a global reality.

Applies the OSE Operative Sequence of Events logic, which allows recording of maneuvers operationsload transfers and xreg restoration at High and Medium Voltage levels. Rewards for good reliability can be implemented in a similar way. On the other hand, the ITAD behavior for the first study was fitted to a gamma function of probability density. 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.

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. The generation technologies that wish to be studied for each DG unit, depending on the primary energy sources available at the installation site. Energy supplied by DG sources. These variables allow evaluating the behavior on the electricity bill of each system customer, and the behavior on financial benefits or penalties for the electric utility due to reliability supplied.

Based on the results presented in Table 3 and Figure 5it was observed that without DG interconnected to test system, the estimated value of the ITAD reliability index came within the dead zone for the incentives scheme or zone number three Z3.

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. Methods for Reliability Assessment The object of electrical network reliability assessment is to determine indexes reflecting the electricity continuity on distribution systems, substations, circuits or defined regions.

Evaluating and comparing the electricity bill of each customer, for the two operation schemes with and without DG. If reliability is better than the dead zone boundary Z1a bonus is given. Energy supplied by power system. This information consists of the investment and generation costs of each technology, which are presented in Table 2 Corredor, Iterative Simulation Procedure The computational tool which was designed for implementing the proposed methodology Luna, Parra, is summarized below: On the other hand, the statistical parameters assumed for lines were obtained from the Billinton test distribution circuit Billinton, Allan,where the failure rates are proportional to the length.

Methodology for assessing the impacts of distributed generation interconnection This contract consists of giving such customers a portion of the profit received by the utility due to the implementation of the incentives and compensations scheme. Hence, some countries have modified their regulatory policies to promote the installation of DG systems, allowing such plants to become competitive compared to large-scale generators.

This reference period led to determining among others, the dead zone for the incentives scheme that is shown in Figure 5.

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. The purpose of this analysis is to explain that, the DG interconnection in distribution systems may cause that the energy bill of passive customers increases or decreases, with respect to the operation scheme without DG.

For example, from the 3. In OMS, the network map is geographically visualized. Related Articles

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.

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.
