A Distribution System Operator (DSO) might consider a capacity contract as a planning alternative to defer grid investments. A Virtual Power Plant (VPP) might be able to provide such capacity and change its production as requested by the DSO. This article presents an assessment of the impact of this type of distribution capacity contract (DCC) on VPP's remuneration. This assessment is done by comparing...
Power systems evolution to an intelligent energy system - smart grid, encounters several issues when integrating distributed generation and demand response. At the aggregator level, activities such as the energy resource management, capacities aggregation and resources remuneration are needed. The present paper addresses the previous needs of the aggregator by considering an optimization of the resources...
In the present context the distribution networks are characterized by the increasing penetration of Distributed Generation (DG) resources, which imposes important changes in operation practice. Moreover, the concept of Demand Response (DR) is currently a very important resource. The present paper proposes a methodology that makes possible the allocation of fixed costs in distribution networks considering...
The development of demand response programs has been allowing to improve power system performance in several ways, both in terms of the management of electricity markets, as well as regarding benefits in its operation. In order to model the remuneration for the participation of consumers in the scheduling of resources, this paper proposes a methodology based on the use of four incentive-based tariffs...
The increasing use of Distributed Generation (DG) resources, as well as the introduction of Demand Response (DR) resources has motivated significant changes in the context of competitive electricity markets and smart grids. The methodology proposed in this paper aims to allow scheduling the DG and DR programs resources, considering the implementation of distinct approaches for DR programs remuneration,...
The distribution generation and demand response remuneration practices, used by most aggregation entities, considers simple characteristics as the type of resource. This evaluation may cause a non optimized tariff definition in most cases. For this paper, a Virtual Power Player as aggregator is considered, which is able to make clusters of both producers and consumers. The proposed methodology defines...
Power systems have been through deep changes in recent years, namely with the operation of competitive electricity markets in the scope and the increasingly intensive use of renewable energy sources and distributed generation. This requires new business models able to cope with the new opportunities that have emerged. Virtual Power Players (VPPs) are a new player type which allows aggregating a diversity...
The question about how wind energy can be remunerated after the end of feed-in tariff schemes still remains unanswered in Portugal. Presently, the majority of wind energy promoters are connected through a point of common coupling, with a defined capacity attribution. In return, these promoters are rewarded with a premium rate (i.e., a feed-in tariff) for a limited amount of time or energy delivered...
