Demand Response Strategy Based on Reinforcement Learning and Fuzzy Reasoning for Home Energy Management
As energy demand continues to increase, demand response (DR) programs in the electricity distribution grid are gaining momentum and their adoption is set to grow gradually over the years ahead. Demand response schemes seek to incentivise consumers to use green energy and reduce their electricity usage during peak periods which helps support grid balancing of supply-demand and generate revenue by selling surplus of energy back to the grid. This paper proposes an effective energy management system for residential demand response using Reinforcement Learning (RL) and Fuzzy Reasoning (FR). RL is considered as a model-free control strategy which learns from the interaction with its environment by performing actions and evaluating the results. The proposed algorithm considers human preference by directly integrating user feedback into its control logic using fuzzy reasoning as reward functions. Q-learning, a RL strategy based on a reward mechanism, is used to make optimal decisions to schedule the operation of smart home appliances by shifting controllable appliances from peak periods, when electricity prices are high, to off-peak hours, when electricity prices are lower without affecting the customer’s preferences. The proposed approach works with a single agent to control 14 household appliances and uses a reduced number of state-action pairs and fuzzy logic for rewards functions to evaluate an action taken for a certain state. The simulation results show that the proposed appliances scheduling approach can smooth the power consumption profile and minimise the electricity cost while considering user’s preferences, user’s feedbacks on each action taken and his/her preference settings. A user-interface is developed in MATLAB/Simulink for the Home Energy Management System (HEMS) to demonstrate the proposed DR scheme. The simulation tool includes features such as smart appliances, electricity pricing signals, smart meters, solar photovoltaic generation, battery energy storage, electric vehicle and grid supply.Peer reviewe

When Europe encounters urban governance: Policy Types, Actor Games and Mechanisms of cites Europeanization
This paper examines European Union (EU) causal mechanisms and policy instruments affecting the urban domain throughout the lenses of the Europeanization approach. Instead of looking at EU instruments that are formally/legally consecrated to cities, we use theoretical public policy analysis to explore the arenas and the causal mechanisms that structure the encounters between the EU and urban systems of governance. Policy instruments are related to policy arenas and in turn to different mechanisms of transmission thus originating a typology of European Policy Modes. The paper focuses on four different EU instruments in the in the macro-area of sustainable development and proposes potential game-theoretical models for each of them.
In the conclusions we highlight the differences between this approach and the traditional analysis of EU urban policy, and suggest avenues for future empirical research based on typologies of policy instruments and modes of Europeanization
Rethinking capital mobility, re-regulating financial markets
The globalisation hypothesis has altered many of the common-sense ‘truths’ around which the social world is organised.* In particular, globalisation is thought to restrict the parameters of the politically and economically possible. Indeed, the notion of constrained choice is so pronounced that we are increasingly confronted with the image of globalisation’s ‘logic of no alternative’; an image which is predicated on the assumption of perfect capital mobility. Capital is considered to be sufficiently rational to take advantage of enhanced exit options from the national economy in circumstances in which its interests are served by moving off-shore. Moreover, global markets are also assumed to have exploited contemporary technological developments to such an extent that they now clear instantaneously; consequently, allowing capital to further its interests wherever in the world new profit opportunities arise. Thus, we are presented with the fundamental ‘reality’ of globalisation as currently narrated throughout much of the west: unless the market can be allowed to restore a competitive global equilibrium, capital will exit high-wage, high-cost western economies and re-locate in lower-wage, lower-cost, newly industrialising economies. Under the auspices of ever more hostile wage competition from the newly industrialising economies, globalisation is commonly presumed to act as a trigger for an ‘inevitable’ job displacement effect as capital deserts the advanced industrialised economies
