An Innovative Planning Method for the Optimal Capacity Allocation of a Hybrid Wind–PV–Pumped Storage Power System

Abstract

In recent years, wind and photovoltaic power (PV) have been the renewable energy sources (RESs) with the greatest growth, and both are commonly recognized as the major driving forces of energy system revolution. However, they are characterized by intermittency, volatility and randomness. Therefore, their stable and efficient implementation is one of the most significant topics in the field of renewable energy research. In order to improve the stability of RESs and reduce the curtailment of wind and solar energy, this paper proposes an innovative planning method for optimal capacity allocation. On one hand, a new power generation system is introduced which combines a pumped storage power station with a wind farm and PV; on the other hand, the sequential Monte Carlo method is utilized to analyze the economy and reliability of the system under different capacity configurations considering investment cost, operating characteristics and influence factors of wind and solar energy. Then, optimal capacity allocation can be achieved. In summary, this proposed scheme provides an effective solution for the planning and construction of a new power generation system with RESs.

Bi-Level Optimal Capacity Planning of Load-Side Electric Energy Storage Using an Emission-Considered Carbon Incentive Mechanism

“…The objective is to maximize the EES net profit as (21). Specifically, the cost of the EES includes the investment cost and operation and maintenance cost as (24) and (25), and the benefit of the EES includes time-of-use tariff arbitrage income as (22), the carbon incentive mechanism subsidy as (10), and the recyclable value of EES devices as (23).…”

“…The existing research on electric energy storage (EES) capacity planning under different scenarios is sufficient [13][14][15][16][17][18]. In addition, there are also studies on capacity planning for thermal energy storage [19,20] and mechanical energy storage [21,22]. In recent years, the collaborative planning of hybrid energy storage capacity has become a new research point.…”

Research on the Internal Flow Characteristics of Pump Turbines for Smoothing the Output Fluctuation of the Wind–Photovoltaic Complementary System

“…In summary, the current research on wind-PV-PHES complementary systems (Dianellou et al, 2021) only involves capacity allocation (Xu et al, 2019) and scheduling optimization (Zare Oskouei and Sadeghi Yazdankhah, 2015). Most of the studies on the characteristics of pumped turbines have been carried out in the context of traditional PHES technology.…”

A Coordinated Dispatching Model Considering Generation and Operation Reserve in Wind Power-Photovoltaic-Pumped Storage System

“…Aiming at the complementary power generation technology of the new energy system and energy storage system, the present research mainly focuses on the optimization operation of the joint system. Reference [6] established a wind-photovoltaic-pumped storage complementary power generation system under the condition of an isolated network operation, which compared and analyzed the operation status of PSPSs with different capacities, and determined an optimal determination method of pumped storage capacity. Reference [7] studied the problem of wind-photovoltaic-pumped storage system's uncertain unit commitment, based on the parameter estimation method to obtain wind-solar output interval, using scene method to describe the uncertainty of wind-photovoltaic output, proposed the binary artificial sheep algorithm (BASA) algorithm to solve it, and verified the validity of the model.…”
