With the integration of distributed renewable energy sources (DRES) and active demand (e.g., units providing demand response, DR) in the distribution grid, the importance of monitoring the network conditions, managing the line congestions and observing the voltage levels is increasing. The distribution system operator (DSO) needs a mechanism, such as the traffic light system, to screen and approve...
The widespread investments in renewable energy sources (RES) in the last 10 years has created a huge burden on the national RES funds due to the flaws in the initial RES support schemes and therefore scheme restoration was inevitable. In the meantime the situation at the energy market has changed radically, some RES technology costs reached grid parity and the development of other complementing technologies...
The increased integration of PV systems in the low voltage network causes many problems in network operations. The EU project STORY is tackling these problems with adding energy storage to the grid. In this paper we present new control concept with peak demand control algorithm which is used on storage unit in LV distribution network. The algorithm development is based on real measurements from transformer...
Market power and its possible abuse by market participants is one of the main issues in electricity trading and a lot of work is done on establishing trading rules for fair and transparent electricity market. The focus of this paper is to present market power detection techniques which have been proposed in literature with detail review of the tools which could be used in monitoring units of organised...
With the development of new smart grid control technologies, the number of load participating in the demand response (DR) programs is increasing. While the flexible capacity these units are providing could be aggregated and scheduled to serve various purposes, it is currently mostly used for reducing final consumer electricity costs. If the schedules of this flexible capacity aren't aligned during...
The accelerated development of renewable energy sources (RES) technology and their enhanced integration into the low voltage (LV) distribution network require changes in the network operational procedures. New technologies like smart inverters developed within EU FP7 project INCREASE have been developed in order to help the Distribution System Operators (DSO) in keeping the network parameters within...
The rising share of the distributed renewable energy sources (DRES) is posing specific challenges regarding their integration in distribution networks. They lead to overvoltages, current congestion and other issues that reduce the power quality and the security of the supply. New solutions are needed especially in the low voltage (LV) networks where the majority of the small-scale DRES are connected...
To reach their renewable energy goals, the EU Member States need a sustained expansion of new renewable energy sources (RES) generation units. In recent years, the investment in RES units in EU, especially PV plants, have been encountering new financing barriers, in particular due to dwindling national budgets available for supporting the RES expansion, leading to reduction of the Feed-in tariffs...
With the adoption of Regulation (EU) No. 1227/2011 on Wholesale Energy Market Integrity and Transparency (REMIT), the European Agency for the Cooperation of Energy Regulators (ACER) took on unprecedented powers to monitor the wholesale energy markets in the EU. The aim of this paper is to give an overview of current development of the framework for monitoring of the wholesale electricity and gas markets...
