Abstract
In order to ensure joint operation of wind-PV-hydro complementary generation system with cascade hydro-power owned by multiple stakeholders, an equitable and efficient allocating mechanism for incremental benefit is of great importance. Firstly, the incremental benefit from joint operation is quantified for wind-PV-hydro complementary generation system with cascade hydro-power owned by multiple stakeholders in this paper. Then, different allocation methods such as proportional method, marginal benefits method, last addition method, Shapley value method, and Aumann-Shapley value method are applied to allocate the incremental benefit for each stakeholder. Next, a 4-stakeholder wind-PV-hydro complementary generation test system is employed to investigate the advantages and disadvantages of the presented different allocation methods and a 9-stakeholder wind-PV-hydro complementary generation test system is used to verify that Aumann-Shapley value method can reduce computational burden with regard to the participation of large number of stakeholders compared with traditional cooperative game-based method such as Shapley value method.
Highlights
With the rising demand for clean energy, high-penetration renewable energy resource will be of great importance in future generation system [1]
ALLOCATION METHODS FOR INCREMENTAL BENEFIT OF WIND-PV-HYDRO GENERATION SYSTEM Here, proportional method, marginal benefits method, last addition method, Shapley value method, and AumannShapley value method are applied to allocate the incremental benefit from joint operation of wind-PV-hydro complementary generation system with cascade hydro-power
SIMULATION RESULTS The tests have been implemented on a laptop computer with 1.60 GHz processors and 8.0 GB of RAM, MILP based optimal wind/PV/hydro operation models are solved by CPLEX 12.4 while allocating problems are solved by MATLAB 6.1 and LINGO 11
Summary
With the rising demand for clean energy, high-penetration renewable energy resource will be of great importance in future generation system [1]. Generation technologies such as wind power generation, photovoltaic (PV) power generation and cascade hydro-power generation are growing rapidly [2]. Abreu et al [9] developed a risk-constrained wind and cascade hydropower joint operation model aims to firm up the hourly dispatch in a generating company. Wang et al [10] established a windPV-hydro joint operation model and results of a case study in southwestern China shown that hydro-power can both alleviate short-term fluctuations (e.g. hourly variations) and long-term fluctuations (e.g. intraday peak-valley differences)
