The difference between demand-side response and virtual energy storage

What is the difference between a demand response and a VPP?

Another semantic difference is which side of the demand-supply curve it’s considered to be on. According to a document cited by the Institute of Energy Economics in Japan, demand response is a demand-side initiative; a VPP is a supply-side initiative. But in practice, this doesn’t equate to much of a distinction.

Can virtual storage plants integrate PEVs into energy grids?

As the incorporation of RES in supplying aspects and Plug-in Electric Vehicles (PEVs) on the load side rises, a heightened variability emerges in the power system's operations. This research introduces an innovative framework for Virtual Storage Plants (VSP) designed to amalgamate the repository capabilities of PEVs into energy grids.

What are virtual power plants & virtual storage plants?

Virtual Power Plants (VPPs) and Virtual Storage Plants (VSPs) are the main tools to solve these problems. These virtual entities allocate Distributed Generation (DG), energy storage systems (ESS), and flexible energy demand to the grid to improve grid stability, efficiency, and reliability.

What is a demand response asset (VPP)?

VPPs such as the one being operated by Enel X in Taiwan are essentially based on demand response, with loads forming the majority of its megawatts. For this reason, it is probably easiest nowadays to think of demand response assets as simply one type of flexible unit that can be incorporated into a VPP.

What is a Virtual Storage Plant (VSP)?

This research introduces an innovative framework for Virtual Storage Plants (VSP) designed to amalgamate the repository capabilities of PEVs into energy grids. The proposed VSP consists of intelligent points for recharging a Parking Lot Aggregator (PLA), a Local Service Provider (LSP), and a Global Service Provider (GSP).

How does a demand curve affect the price of renewable power?

The more the slope of the demand curve, more the flexibility, means to change a larger amount of load in response to a smaller amount of price. In case of renewable, the supply price curve moves to the right. In turn, the price reduces. The opposite could happen; when renewable power generation decreases, the price becomes higher.
