Aggregator's business models: Challenges faced by different roles

Aggregators are considered essential to obtain flexibility from small residential and service sector consumers. They can implement business models by trading flexibility from their consumers' assets in various electricity markets. The aim of this paper is to identify challenges faced by aggregators with different roles, while implementing...

The effect of price-optimized charging on electric vehicle fleet emissions

Aggregation of sufficiently large electric vehicle (EV) fleets and control over their charging schedules enables aggregators to utilise the flexibility of EV charging in the Day Ahead Market. Optimising the charge scheduling of such fleets enables time-shifting of electricity demand to hours when electricity is cheaper, reducing the...

Reduction of price volatility using thermostatically controlled loads in local electricity markets

Price volatility in electricity markets could significantly increase as a result of the increase in demand due to the electrification of heating and transport and intermittent power generation from large scale integration of renewable energy sources. In some parts of the grid, price volatility may be even more extreme due to congestion....

Segmented energy tariff design for flattening load demand profile

In this paper, a segmented energy tariff design is proposed to incentivize consumers to flatten load demand. This energy tariff focuses on consumption levels instead of consumption periods. Energy storage is an effective strategy to help to maintain the imported energy from grid below the threshold without affecting the comfort of energy...

Challenges for the design of a Vehicle-to-Grid Living Lab

This paper outlines the challenges faced during the implementation of a Vehicle-2-Grid set-up from the design phase, through project planning, application for permits and clearances, procurement of equipment and installation. It is based on the experience of designing a living lab at the Green Village in TU Delft, the Netherlands. Desk...

The Role of Demand-Side Flexibility in Hedging Electricity Price Volatility in Distribution Grids

Locational Marginal Price (LMP) is a dual variable associated with supply-demand matching and represents the cost of delivering power to a particular location if the load at that location increases. In recent times it become more volatile due to increased integration of renewables that are intermittent. The issue of price volatility is...

Exploring the potential of the vehicle-to-grid service in a sustainable smart city

The vehicle-to-grid (V2G) service is slowly gaining momentum in its capacity to engage as a means of distributed generation. An aggregator's role is pivotal in the need to coordinate vehicles for V2G and maintain the security of supply of its customer base. The paper focuses on comparing the performance of the energy system when an aggregator...

Critical Analysis of the Profitability of Demand Response for End-Consumers and Aggregators with Flat-Rate Retail Pricing

Aggregators are considered essential to extend demand response (DR) to small residential and service sector consumers. Both sectors currently have untapped load flexibility, which is considered key to support renewable resource integration. Aggregators can offer this flexibility in bulk to other power system parties. This paper addresses the...

Exploring the profit potential of energy storage in a car park using electrolysis, hydrogen storage and fuel cell electric vehicles

The Car Park as Power Plant (CPPP) is a main business concept related to a future integrated sustainable mobility and energy system in which hydrogen is a key energy carrier. In order to investigate the uncertain profitability of the CPPP concept, an optimisation model has been developed of a CPPP system that includes an electrolyser, a hydrogen...

Daily storage management of hydroelectric facilities

This work presents a management procedure for hydroelectric facilities with daily storage. The water storage gives an additional degree of freedom allowing to shift in time power production when it is more convenient and to work at the maximum efficiency of hydraulic turbine. The management is optimized by coupling two different approaches:...

Acceptance of Privacy-Sensitive Technologies: Smart Metering Case in The Netherlands

Over recent years there have been several initiatives around the world that aim to roll out smart metering systems, especially within North America and member states of the European Union. Smart metering systems, giving essential conditions for smart grids in the energy sector, can offer services aimed at achieving many different goals beyond...

Shippers and Network Capacity Booking in the Dutch Gas Market

The main objectives of the Third Gas Directive (2009/73EC) approved by the European Union are: unbundling, creating an independent Transport Service Operator (TSO) and ensuring free access to the market. The separation of gas trading from transportation activities required new market rules and gas balancing. Thereby, the TSO's responsibilities...

Over recent years there have been several initiatives around the world that aim to roll out smart metering systems, especially within North America and member states of the European Union. Smart metering systems, giving essential conditions for smart grids in the energy sector, can offer services aimed at achieving many different goals beyond...

A non-iterative cascaded predictive control approach for control of irrigation canals

Irrigation canals transport water from water sources (such as large rivers and lakes) to water users (such as farmers). Irrigation canals are typically very large in nature, covering vast geographical areas, and involving a significant number of control actuators, such as pumps, gates, and locks. The control of such canals is aimed at...
