On 30th of June 2015 the European Network of Transmission System Operators for electricity (ENTSO-e) published the ENTSO-e Scenario Outlook & Adequacy Forecast (SOAF) report providing information about impact of Renewable Energy Sources (RES) on power system and potential lack of flexibility in power systems of thirty seven European countries. The flexibility is measured using Residual Load (RL)...
The aim of the paper is maximization the consumption of energy generated by RES in distribution system. It is achieved by aggregation of loads and power generating units to common internal grid called power park. In order to maximize consumption of renewable energy, the RES sizing optimization model is used. In order to reflect the intermittency of renewables, they are modelled by generation profiles...
This paper presents a comparative analysis of energy storing and renewable generation curtailment as a measures for minimization of energy costs under defined share of renewables. Application of both measures allow to solve the issues of the night over-generation, that is one of the reason of limited capacity of grid connections for renewables. Both energy storing and generation curtailment are examined...
The paper objective is the review and proposal for enhancement of the system flexibility-related calculations in the recent release of Scenario Outlook & Adequacy Forecast 2015 by ENTSO-E. The document presents generation adequacy assessments and introduces residual load and RES ramping analyses as new elements in flexibility calculations. This research focuses on the evaluation of the ENTSO-E...
The aim of the paper is maximization of the Renewable Energy Sources (RES) generation in distribution network by its sizing and allocation, taking into account variable RES production. The objective function is annual energy generated by local RES calculated as a product of the power units rated power (control variable) and annual availability factor. In order to include technical constraints (such...
