Demand response within the energy-for-water-nexus - A review. ESRI WP637, October 2019

A promising tool to achieve more flexibility within power systems is demand re-sponse (DR). End-users in many strands of industry have been subject to research up to now regarding the opportunities for implementing DR programmes. One sector that has received little attention from the literature so far, is wastewater treatment. However, case studies indicate that the potential for wastewater treatment plants to provide DR services might be significant. This review presents and categorises recent modelling approaches for industrial demand response as well as for the wastewater treatment plant operation. Furthermore, the main sources of flexibility from wastewater treatment plants are presented: a potential for variable electricity use in aeration, the time-shifting operation of pumps, the exploitation of built-in redundan-cy in the system and flexibility in the sludge processing. Although case studies con-note the potential for DR from individual WWTPs, no study acknowledges the en-dogeneity of energy prices which arises from a large-scale utilisation of DR. There-fore, an integrated energy systems approach is required to quantify system and market effects effectively

Distribution market as a ramping aggregator for grid flexibility support

The growing proliferation of microgrids and distributed energy resources in distribution networks has resulted in the development of Distribution Market Operator (DMO). This new entity will facilitate the management of the distributed resources and their interactions with upstream network and the wholesale market. At the same time, DMOs can tap into the flexibility potential of these distributed resources to address many of the challenges that system operators are facing. This paper investigates this opportunity and develops a distribution market scheduling model based on upstream network ramping flexibility requirements. That is, the distribution network will play the role of a flexibility resource in the system, with a relatively large size and potential, to help bulk system operators to address emerging ramping concerns. Numerical simulations demonstrate the effectiveness of the proposed model on when tested on a distribution system with several microgrids.Comment: IEEE PES Transmission and Distribution Conference and Exposition (T&D), Denver, CO, 16-19 Apr. 201

Water Marketing as an Adaptive Response to the Threat of Climate Change

Demographic changes and existing water use patterns have placed tremendous pressures upon water supplies, particularly in the West. Global climate change will exacerbate pressures on water resources. The gradual warming of the atmosphere is certain to change the distribution and availability of water supplies, with potentially severe consequences for freshwater supplies. While climate change will have a significant impact on water resources through changes in the timing and volume of precipitation, altered evaporation rates, and the like, the precise nature, magnitude, timing, and distribution of such climate-induced changes are unknown. This uncertainty complicates the task of water managers who are already faced with escalating demands. This article argues that climate change, and its projected effects on water use and supply, calls for a fundamental reexamination of water institutions. In particular, this article suggests that market-based institutions are well suited to address the additional pressures on water supplies due to climate change. Many aspects of water markets, including their flexibility, decentralized nature, and ability to create and harness economic incentives, make them particularly well suited to address the uncertain water forecast. A gradual shift toward water marketing and market pricing will improve the management of water supplies, ensure more efficient allocation of available water supplies and encourage cost-effective conservation measures

BUILDING COMPETITIVE ADVANTAGE THROUGH MARKETING, MANUFACTURING AND ENVIRONMENTAL MANAGEMENT STRATEGY: A CASE STUDY OF METAL PRODUCT SMEs IN TEGAL

This research investigates how the marketing strategy, manufacturing strategy and environment management create SMEs competitive advantage that will improve SMEs business performance. It gives both theoretical and managerial implications about steps must be taken by SMEs to improve their business performance through the competitive advantage gained from the marketing strategy, manufacturing strategy, and the ability to manage the environment. This research includes a data set from 121 SMEs. Results show that the manufacturing and environment management strategy positively affects SMEs competitive advantage, and the competitive advantage also positively affects SMEs business performance. Marketing strategy implemented didn’t affect the competitive advantage. This research proved that for now, the competitive advantage of metal product SMEs in Tegal lay on their ability to create product in accordance with consumers want. Metal SMEs always maintain their flexibility and product quality with competitive prices. To gain the competitive advantage, SMEs must have the ability to adjust with political and economics transformation such as general election or city major and governor transformation. Because of its flexibility, metal SMEs in Tegal can easily adjust with the transformation of political and economical climate. The last thing that must be noted from this research is that metal SMEs in Tegal didn’t implement the marketing strategy well because of the job-order system. The competitive advantage will be more perfect if the company also have superb marketing strategy
