Definition of Scenarios and Reference Cases

About

Work package 2 – Definition of scenarios and reference cases – aims to establish a reference framework that describes the demands hydropower plants are going to be confronted with in future transmission grids. The focus will be on identifying the dynamic loads such as those resulting from providing high ramping rates and frequent start-stop cycles.

One outcome of this work package will be a guide describing the requirements hydropower plants in Europe must meet in the future. For the final recommendations, the guide will provide information about the financial benefits resulting from providing fast ancillary service. The guide will give important contributions to the transmission system operators and other entities involved in the planning and development of the power system.

Objectives

This work package aims to identify and describe the demands that hydropower plants will be confronted with in future power systems. In particular, WP 2 includes:

• The definition of three European energy scenarios
• The identification of hydropower plants as reference sites to describe the future dynamic operating conditions hydropower plants can experience
• The calculation and simulation of the future requirements for the identified reference sites
• The development of a guide describing the future requirements for hydropower plants, the specific design considerations and technical implications for power plants developers.

Tasks

2.1. Energy scenarios

Three global – in a European scope – energy scenarios are defined with respect to different generation and transmission situations in the power system. First, relevant parameters are identified. Second, a meta-analysis of existing scenario studies will be performed.

2.2. Reference sites

A set of generalized reference cases is created which describes common and special dynamic events as the relevant criteria for the operation of hydropower plants. This also includes the definition of quality indicators to characterize the operational flexibility of hydropower plants.

2.3. Calculation and simulation

The generalized references cases will be selected and parameterized for every defined scenario. Subsequently, these parameterized reference cases will be used to perform market simulations and calculate the resulting power flows within the European grid for selected scenarios.

2.4. Guide describing demands for flexible hydropower

Scenarios, reference cases and the results of calculations and simulation will be merged and transformed into a guide describing the operational requirements hydropower have to meet in the future.
