“…In this subsection, the DMPC optimization algorithm is presented. The algorithm code was written in MATLAB ® , using the optimization routine (fmincon) in order to find the optimal power sequence for each house (Equation (14)), subject to the constraints (Equations (16)- (19)). The agents set their bid prices a day-ahead, indicating how much they are willing to pay in order to consume clean energy.…”

This work reports a contribution, in a model predictive control multi-agent systems context, introducing a novel integrative methodology to manage energy networks from the demand-side point of view, in the strong presence of intermittent energy sources, including energy storage in households or car batteries. In particular, the article presents a control-based solution for indoor comfort, which, in addition, optimizes the usage of a limited shared energy resource. The control management is applied, in a distributed way, to a set of so-called thermal control areas (TCAs) and demand units, with the objective of minimizing the cost of energy while maintaining the indoor temperature within the comfort zone bounds, and simultaneously not exceeding a limited amount of shared renewable energy. The thermal control areas are, in general, thermodynamically connected, and are also coupled by energy interrelation constraints established in the particular optimization solution. Energy management is performed with a fixed sequential order established from a previously carried out auction, wherein the bids are made by each unit’s demands, acting as demand-side management agents, based on the daily energy price. The developed solution is explained by a basic algorithm that has been applied to different scenarios, and the results have been compared so as to illustrate the benefits and flexibility of the proposed approach, showing less energy consumption and a 37% cost saving.

The International Energy Agency believes that energy efficiency is the most cost-effective way to meet the environmental challenges. ERSE, the Portuguese Energy Services Regulatory Authority, established in 2006 a competitive tender mechanism to promote efficiency in electricity consumption called PPEC. PPEC first edition (PPEC 2007) sponsored 26 measures, implemented during 2007, 2008 and 2009. The benefits were estimated to be 4,6 times higher than the costs. However, the ex-post measurement and verification plans revealed that the benefit cost ratio went well above the expectations, mounting to 7,4.Clearly, competitive tender mechanisms are one of the means possible to ensure sufficient, affordable, reliable energy supply while meeting environmental goals. Regulators ensure the crucial balance between energy availability and energy affordability and thus have a central role in the transition to a low carbon energy sector.

“…budget of the program is supported by the Global Use of System regulated tariff, paid by all consumers and included in third party access tariffs. In this plan, energy efficiency measures are evaluated and ranked by merit order, based on a technical and economical analysis [1]. The evaluation process is based on a metrical criteria related with the amount of energy savings deemed achievable through a given measure.…”

Energy consumption depends on various factors, such as equipment's energy efficiency, comfort level, consumer's behaviour and income. Equipment's efficiency and consumer's behaviour are crucial to achieve energy savings. The present paper focuses on the relation between energy savings and consumer's behaviour. For the majority of demand side management measures, energy savings obtained are affected by behavioural factors, introduced by the consumers. The Portuguese Energy Services Regulatory Authority (ERSE) has developed a competitive mechanism for promoting efficiency in electricity consumption called PPEC (Demand-side Electricity Efficiency Plan). In this plan, energy efficiency measures, promoted by suppliers, network operators, consumers and energy agencies, etc, are evaluated and ranked by merit order. The merit of each measure is defined by a cost-benefit analysis. A methodology to consider the behavioural factors in the merit analysis of energy efficiency measures is presented in the paper.
